 **Converters** 
 
-1. [OpenCVConverter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/OpenCVConverter.kt) - the fastest. If your goal is to get Mat you may consider this method from [OpenCV](https://github.com/opencv/opencv/blob/master/modules/java/generator/android-21/java/org/opencv/android/JavaCamera2View.java#L344).
-2. [RenderScriptConverter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/RenderScriptConverter.kt) - built-in, no additional libraries required.
-3. [MNNConverter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/MNNConverter.kt) - if your goal is futher processing with neural network.
+1. [OpenCVRoteterter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/OpenCVRoteterter.kt) - preform rotation on yuv image and then converts color. **The fastest in total time**.
+2. [OpenCVConverter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/OpenCVConverter.kt) - the fastest color conversion without rotation. Rotation of a rgb image is slightly harder. 
+3. [RenderScriptConverter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/RenderScriptConverter.kt) - built-in, no additional libraries required. Uses Bitmap for rotation.
+4. [MNNConverter.kt](app/src/main/java/ru/gordinmitya/yuv2buf_demo/MNNConverter.kt) - if your goal is futher processing with neural network. Conversion and rotation performed in single operation.

+PS: If your goal is to get Mat you may consider this method from [OpenCV](https://github.com/opencv/opencv/blob/master/modules/java/generator/android-21/java/org/opencv/android/JavaCamera2View.java#L344).
