What is the meaning/purpose of giving CvType when involved with imageslike
"mRgba = new Mat(height, width, CvType.CV_8UC4);"
and there are whole lot of these types... whats their significance? and how to know which one to choose??
This types define color depth, number of channels and channel layout in the image. On Android the most useful are CvType.CV_8UC4 and CvType.CV_8UCq. CvType.CV_8UC4 is 8-bit per channel RGBA image and can be captured from camera with NativeCameraView or JavaCameraView classes and drawn on surface. CvType.CV_8UC1 is gray scale image and is mostly used in computer vision algorithms.
Same question here, where can I find a doc for all these constants? Such as CV_16SC3. I guess it means 16bit per channel, and is signed. But why signed?
