When, default general cutting method is selected as the cutting method cut to the original image.
Alternatively, foregoing method, according to the picture element, selecting for being cut to the original image
Before cutting method, in addition to：When detecting the face from the original image, the quantity of the face is counted；Root
According to the picture element, the cutting method for being cut to the original image is selected, is specifically included：In the original graph
When the quantity of face described in piece is 1, according to cutting method corresponding to face selection.
Alternatively, foregoing method, in addition to：When the quantity of face described in the original image is more than 1, selection is pre-
If general cutting method as the cutting method cut to the original image.
Alternatively, foregoing method, the characteristic element is remained with the Target Photo.
According to another aspect of the present invention, the device that a kind of picture is cut is additionally provided, it includes：Characteristic element detects mould
Block, the original image for treating cutting are detected, and detect the characteristic element included in the original image；Cutting method
Selecting module, for according to the characteristic element, selecting the cutting method for being cut to the original image；Cut mould
Block, for being cut by the cutting method to the original image, to obtain Target Photo.
Alternatively, foregoing device, the characteristic element include the face and/or logotype of personage.
Alternatively, whether foregoing device, the characteristic element detection module are detected in the original image comprising described
Face；And when not including the face in the original image, detect in the original image whether include the figure mark
Will.
Alternatively, foregoing device, the cutting method selecting module do not include the face in the original image
During with the logotype, default general cutting method is selected as the cutting method cut to the original image.
Alternatively, foregoing device, the characteristic element detection module also detected from the original image it is described
During face, the quantity of the face is counted；The quantity of cutting method selecting module face described in the original image
For 1 when, according to the face selection corresponding to cutting method.
Alternatively, foregoing device, the quantity of cutting method selecting module face described in the original image
During more than 1, default general cutting method is selected as the cutting method cut to the original image.
Alternatively, foregoing device, the characteristic element is remained with the Target Photo.
Technical scheme more than, it is known that the method and apparatus that picture of the invention is cut at least have advantages below：
Technique according to the invention scheme, original image is detected first before picture is cut, detected wherein
Comprising characteristic element, and cut according to the difference of characteristic element using different cutting methods, so as to ensure for
Different pictures can use suitable cutting method in time so that the Target Photo for cutting to obtain meets demand.
Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention,

Embodiment
The exemplary embodiment of the disclosure is more fully described below with reference to accompanying drawings.Although the disclosure is shown in accompanying drawing
Exemplary embodiment, it being understood, however, that may be realized in various forms the disclosure without should be by embodiments set forth here
Limited.On the contrary, these embodiments are provided to facilitate a more thoroughly understanding of the present invention, and can be by the scope of the present disclosure
Completely it is communicated to those skilled in the art.
As shown in figure 1, providing a kind of method that picture is cut in one embodiment of the present of invention, it includes：
Step 110, the original image for treating cutting is detected, and detects the characteristic element included in original image.
In the present embodiment, the type of characteristic element is not limited, it includes but is not limited to the face of personage and logotype, example
Such as, commodity, the mark of enterprise.
Step 120, according to characteristic element, the cutting method for being cut to original image is selected.In the present embodiment
In, cutting method is not limited, for example, characteristic element is its face in portrait photographs, then corresponds to cutting method to cut
The picture of face is included down；Characteristic element has been the figure or background colour of marked effect in merchandise marks picture, then picture is complete
Portion's content, which is copied in certain area, to be cut, and remaining region when copying picture is filled with background colour.
Step 130, original image is cut by cutting method, to obtain Target Photo.According to the skill of the present embodiment
Art scheme, original image is detected first before picture is cut, detects the characteristic element wherein included, and according to spy
The difference for levying element use different cutting methods to be cut, so as to which ensure can be in time using suitably for different pictures
Cutting method so that the Target Photo for cutting to obtain meets demand.
Further, characteristic element is remained with Target Photo.Because generally characteristic element is in original image
The figure or background colour that play marked effect in face, logotype picture in pith, such as personage's picture, has
Necessity is retained.
According to Fig. 1, personage A news photograph is detected, based on face recognition technology, can detect personage A's
Face；Lower personage A face region is cut when then being cut to photo from photo, remainder is abandoned；Obtained after cutting
Picture in there is personage A face, be advantageous to indicate personage A identity, be engaged with personage A news.
As shown in Fig. 2 providing a kind of method that picture is cut in one embodiment of the present of invention, it includes：
Step 210, detect in original image whether include face.
Step 220, when original image includes face, the cutting for being cut to original image is selected according to face
Mode.
Step 230, when not including face in original image, detect in original image whether include logotype.At this
In embodiment, face has higher detection priority compared to logotype, because having face and figure mark simultaneously
The picture of will, the content generally mainly presented are faces, so preferentially detecting face to be cut.
Step 240, when original image includes logotype, select to be used to cut out original image according to logotype
The cutting method cut.
Step 250, when not including face and logotype in original image, default general cutting method conduct is selected
The cutting method cut to the original image.In the present embodiment, general cutting method is not limited, carried herein
For a kind of cutting method for adapting to more multi-class picture：Level specific pressure contracting, minimum contracting are carried out by minimum compression ratio to original image
Put as follows than calculation formula：
Min_scale=MIN (widthsrc/widthdst,heightsrc/heightdst)
If the width of unpressed original image and high respectively widthsrc, heightsrc；The width of Target Photo and high difference
For widthdst, heightdst.The pixel that surrounding in picture after scaling is exceeded to Target Photo scope is cropped to obtain target
Picture, this cutting method are advantageous to crop the insignificant marginal portion of original image.
It should be noted that above-mentioned the separate equations are not the unique formula for realizing the present invention, only one as embodiment
Kind implementation.Technical staff can need to do formula appropriate deformation according to business, such as increase constant or variable or coefficient
Etc. mode, still fall within the scope and spirit of the invention.
Step 260, original image is cut by cutting method, to obtain Target Photo.
According to Fig. 2, in the photo of a Star News report, a star gets on or off the bus from vehicle, has logo on vehicle,
Significantly the emphasis of this photo is star；Now it is primarily based on face recognition technology and carries out Face datection, detects star's
Face, then the face of star is cut when being cut, the star can be identified in the picture for cutting to obtain, with
News report is engaged.
