Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that such descriptions are interchangeable under appropriate circumstances such that the embodiments of the disclosure can be practiced in sequences other than those illustrated or described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In the related art, when editing an image or video, a sticker material resource carried by an image or video editing application software application is generally selected for editing. The number of the materials acquired in the above manner is limited, and the user can only change the size or position of the sticker material, but cannot change the content in the material. Such as: the image in the sticker material is in a semicircular shape, and the user wants to use the circular sticker material, but the user cannot edit the semicircular material sticker to be in a circular shape based on the selected sticker material.
In addition, in the related art, it is mentioned that a user can freely scribble on an image or video, that is, by touching a touch screen with a finger, or by using a mouse to draw a picture on the image or video. Although the mode can enable the user to edit the image, the graffiti is not high in fineness and attractiveness, and the ordinary user is difficult to manually make beautiful graffiti. Based on this, the inventor proposes a material processing method to solve the above problems.
Referring to fig. 1, a method for processing materials according to an embodiment of the present disclosure includes:
in step 101, a drawing interface is provided. The drawing interface is a man-machine interaction interface which can receive a corresponding response given by a user to implement drawing operation. The drawing operation performed by the user may include a gesture operation or an operation performed by an external device such as a mouse. The user can randomly scribble on the drawing interface in a sliding touch mode or a mouse dragging mode to obtain the custom pattern. That is, in step 102, a drawing operation performed on the drawing interface may be received, and a custom pattern corresponding to the drawing operation may be obtained. Because different users have different ages, different regional distributions and different culture levels, not all users have the capability of drawing materials and can draw materials suitable for making multimedia resources by themselves, in view of this, in step 103 in the present disclosure, image transformation is performed on the custom pattern according to preset image transformation information to obtain corresponding target materials. That is, no matter what type the user gets the custom pattern by graffiti, whether it is beautiful or not, the custom pattern can be processed according to the preset image transformation information in the disclosure to obtain the target material, for example, the user draws a line, which cannot be called as beautiful or pattern.
For example, when a short video is produced, a user may scrawl through a drawing interface to obtain some messy lines, and then perform image transformation through image transformation information, and then the messy lines may be processed into a pattern, as shown in fig. 2, the pattern on the left side in fig. 2 is the scrawl of the user on the drawing interface, the pattern on the right side is the pattern obtained through the processing by the material processing method, and the obtained pattern is the photo frame in which the target material may be used as each frame image of the short video.
Note that the target material may be pasted at an arbitrary position in the image designated by the user. Of course, target materials may also be added to the newly-created transparent layer, so that a user may process through a separate layer, and specific requirements may be selected according to the user's own requirements, which is not specifically limited in this disclosure.
In addition, the target material can also be used for making video or audio-visual data, and the present disclosure is applicable as long as the purpose of editing images or videos can be achieved by using the target material.
For the convenience of understanding, some keywords related to the present disclosure are described first, and it should be noted that the definitions of the keywords are only used for illustrating the possible meanings of the keywords and are not used for limiting the embodiments of the present disclosure. The preset image transformation information at least comprises an image transformation mode, transformation processing information and superposition processing information, wherein,
image conversion method: i.e. the way in which the pattern can be transformed, such as: rotation transformation, scaling transformation, mirror transformation, affine transformation, and the like.
Transformation processing information: namely, the transformation times of the image transformation modes and the reference transformation information, wherein the reference transformation information is that the custom pattern is transformed into the reference image according to which image transformation modes, and the intermediate pattern is obtained by further transformation according to the reference pattern, such as: the user-defined pattern is subjected to image transformation for 10 times to obtain a reference pattern 1, wherein mirror image transformation is performed for 3 times and rotation transformation is performed for 7 times; the custom pattern undergoes 5 image transformations to obtain the reference pattern 2, wherein the rotation transformation is 4 times and the scaling transformation is 1 time.
Information superposition processing: namely, the method of superimposing the intermediate image is to directly superimpose the intermediate pattern, or to superimpose the intermediate pattern after position conversion. For example: rotating the middle pattern by 360 degrees according to the selected rotation center to obtain a target material 1; and after the mirror image transformation is carried out on the intermediate pattern, the image after the mirror image transformation is superposed with the intermediate pattern, and the target material 2 is obtained through rotation.
Based on the preset image transformation information, step 103 performs image transformation on the custom pattern according to the preset image transformation information to obtain a corresponding target material, and may perform image transformation on the custom pattern according to the image transformation mode and the transformation processing information to obtain an intermediate pattern, and then superimposes the intermediate pattern according to the superimposition processing information to obtain the target material.
In this way, it can be determined on which specific image transformation information the target material is acquired based.
It should be noted that the intermediate pattern is a pattern obtained by image transformation each time, if the image transformation is performed only once, the custom pattern can be directly transformed, and if the image transformation is performed multiple times, the custom pattern can be image-transformed to obtain the intermediate pattern.
Obtaining the intermediate pattern based on any mode, wherein the mode of image transformation is realized by at least one of rotation transformation, scaling transformation, mirror image transformation or affine transformation; if the image transformation mode comprises rotation transformation, the transformation processing information also comprises a mirror image reference line of the mirror image transformation, the mirror image reference line, namely the mirror image transformation, is the axisymmetric transformation based on which symmetric axis is the mirror image reference line. As shown in fig. 3, when the customized pattern is not consistent with the pattern obtained by performing mirror image transformation based on the mirror image reference line 1 and performing mirror image transformation based on the mirror image reference line 2, the mirror image reference line needs to be acquired based on the mirror image transformation to determine the result of the pattern transformation.
If the image transformation mode includes rotation transformation, the transformation processing information further includes a rotation center point position and/or a rotation angle of the rotation transformation, during the rotation transformation, the rotation can be performed with reference to a center point, or the rotation can be performed by a preset angle directly on the basis of the original pattern, or a center point can be selected, the target pattern can be obtained by rotating the preset angle based on the selected center point, during the actual image transformation, a specific rotation transformation mode can be selected according to the actual requirement, and the method is not particularly limited herein.
If the image transformation mode includes scaling transformation, the transformation processing information further includes a scaling ratio of the rotation transformation, and the scaling ratio can be set according to requirements, such as reducing the pattern to 20% of the original pattern, enlarging the pattern to 120% of the original pattern, and the like. The specific scaling ratio can be selected according to actual requirements, and is not specifically limited herein.
If the image transformation manner includes affine transformation, the transformation processing information further includes a translation direction and a displacement distance of the affine transformation. If the pattern is affine transformed, the transformation processing information may be positive direction of the coordinate axis X, and may be set according to actual requirements, and is not specifically limited herein.
Furthermore, it should be noted that the rotation transformation and the scaling transformation may also be implemented by affine transformation. Affine transformation can also implement transformation of translation direction and displacement distance. The affine transformation may also implement a combination transformation of a plurality of image transformations, such as rotation, scaling, translation, displacement, and the like, and which image transformations are specifically adopted may be selected according to actual requirements of a user, which is not specifically limited herein.
Aiming at different image transformation modes, the method corresponds to different transformation processing information, and is convenient for obtaining patterns meeting requirements during image processing.
How to acquire the intermediate pattern by the first and second modes will be described in detail below with reference to the determined image transformation mode.
Method one, acquiring intermediate pattern based on reference pattern
The intermediate pattern is acquired in the mode, wherein in the preset image transformation information, the transformation processing information at least comprises reference transformation information and transformation times of an image transformation mode; the reference transformation information at least comprises the image transformation mode used for generating the reference pattern and corresponding reference transformation parameters, and the reference transformation parameters are used for indicating which image transformations are specifically carried out on the reference pattern and the corresponding image transformation times, such as: the user-defined pattern is subjected to 5 times of rotation transformation to obtain a reference pattern, and the reference transformation parameters are subjected to 5 times of rotation transformation; and (3) the self-defined pattern is subjected to 1-time mirror image transformation, and is subjected to 1-time rotation transformation and is superposed with the self-defined pattern to obtain a reference pattern, and then the reference transformation parameters are subjected to 1-time mirror image transformation, 1-time rotation transformation and superposition of the self-defined pattern. All the parameters which can indicate the transformation process of the custom pattern into the reference pattern are reference transformation parameters, and are suitable for the disclosure, and are not specifically limited herein.
And transforming the custom pattern according to the reference transformation information to obtain a corresponding reference pattern, copying the custom pattern in the graph 4 based on the determined mirror image reference line, then carrying out mirror image transformation, and overlapping the custom pattern to obtain a reference pattern shown in a reference pattern 1 shown in the graph 4, wherein the curve 1 is the custom pattern drawn by a user, and the curve 1 is turned over according to the mirror image reference line to obtain a curve 2, wherein the reference transformation information is mirror image transformation, and the reference transformation parameters are mirror image transformation for 1 time and overlapping. And rotating an image obtained by scaling 20% of the custom pattern in the graph 4 to obtain a reference pattern 2, wherein a curve 1 is the custom pattern, a curve 1 is the reference pattern 2 obtained by scaling and rotating after copying, a curve 3 is the reference pattern 2 obtained by scaling and rotating, the reference transformation information is scaling transformation and rotating transformation, the reference transformation parameters are scaling transformation and rotating transformation for 20% of times and rotating transformation for 1 time. And then, converting the reference pattern according to the image conversion mode and the corresponding image conversion times to obtain a corresponding intermediate pattern.
The intermediate pattern obtained based on the method is simple and convenient to operate, and the pattern editing mode is enriched.
Second, intermediate pattern is obtained based on initial transformation pattern
Based on the intermediate pattern obtained in this way, if the image transformation manner includes at least two of rotation transformation, scaling transformation, mirror transformation, or affine transformation, the transformation processing information further includes transformation orders between different image transformation manners and an initial transformation pattern for each image transformation manner, the initial transformation pattern includes the custom pattern or an intermediate pattern obtained by transformation in other different image transformation manners, wherein the transformation order in the transformation processing information here is an execution order of the image transformation manners, the initial transformation image is a pattern before the image transformation manner is executed, the initial transformation patterns corresponding to different operation timings are different, the pattern before mirror transformation of the reference pattern 1 in fig. 4, that is, the custom pattern, is the initial transformation pattern, and for the reference pattern 2 in fig. 4, the pattern before the rotation transformation, i.e. the pattern scaled by 20% from curve 1, is the initial transformation pattern (not shown in the figure, and only a brief description is given here for understanding).
And according to the conversion sequence, sequentially using the corresponding image conversion mode and the conversion processing information to convert the corresponding initial conversion pattern to obtain the corresponding intermediate pattern.
The intermediate pattern obtained by the method increases the pattern editing mode, and further enables the generated target material to be more diversified.
The target material can be obtained based on the obtained intermediate pattern, and when the target material is executed, the information of the superposition processing includes a position relation parameter between any two intermediate patterns, wherein the position relation parameter is used for representing the position relation between the two intermediate patterns, as shown in fig. 4, a curve 1 and a curve 2 can be regarded as the two intermediate patterns, the curve 1 and the curve 2 are symmetrically distributed by a mirror image reference line and can be regarded as the position relation parameter of the two intermediate patterns, and when the target material is actually applied, the target material further includes a relative change angle, a displacement and the like of the intermediate patterns.
And setting the superposition position of the corresponding intermediate pattern according to the position relation parameter, and then superposing the intermediate pattern according to the corresponding superposition position to obtain the target material. For the reference pattern 1 in fig. 4, it is determined that the curve 1 and the curve 2 are symmetrical about a mirror image reference line, and three lines intersect at the point a and the point B, the reference image in fig. 4 is copied and rotated with the point B as a rotation center to obtain an intermediate pattern shown in fig. 5, the image in the reference pattern 1 as a whole is copied, then the copied image is rotated by a certain angle (the angle is counted as θ, such as 36 °), and then copied again, and the copied image is rotated by 2 times θ, and the copying and rotation are repeated n times, where n × θ is 360 °, which is exactly one cycle, and 3 times to obtain the intermediate pattern shown in fig. 5, and the target material 1 shown in fig. 5 is obtained by one cycle of rotation. The target material 2 shown in fig. 5 can be obtained by adjusting θ to 18 °.
Note that since only a single intermediate pattern is included in the reference pattern 2 shown in fig. 4, the positional relationship parameter does not exist, and the target material 3 shown in fig. 5 can be obtained by performing a plurality of times of rotational transformations on the image shown in fig. 4.
The target material obtained by the method has more diversified editing modes.
In one embodiment, the intermediate patterns meeting the preset condition can be selected, and the target material can be obtained by overlapping according to the overlapping processing information. It should be noted that, after a user-defined pattern drawn by a user is called as an intermediate pattern through image transformation, an attractive pattern may not be generated, the material processing method may pre-judge the intermediate pattern, prompt the user that the part in the intermediate pattern may be unfavorable for generating a target material, and give a prompt operation so that the user selects the intermediate pattern meeting a preset condition, thereby generating the target material, the intermediate pattern shown in fig. 6 is composed of a curve 1 and a curve 2, and the terminal, through analysis of the intermediate pattern, prompts that the curve 1, the curve 1 and the curve 2 cannot be combined, and proposes to delete the curve 2; 2. the line suggestion in the dashed box is reserved, and the user can select the operable part in the middle pattern according to the information prompt to generate the target material.
