public void onCameraViewStarted(int width, int height) {
mRgba = new Mat(height, width, CvType.CV_8UC4);
mIntermediateMat = new Mat(height, width, CvType.CV_8UC4);
mGrayMat = new Mat(height, width, CvType.CV_8UC1);can someone explain me what are these CvType.CV_8UC4 and CV_8UC1??? this is from the tutorials provided by opencv for android
Basically it describes the format that you are creating.
A matrix of type CV_8UC4 contains
For the C1, this means you want a grayscale image with just a single color channel containing intensities between 0 and 255.
Just in case, I haven't read the Java documentation yet. But just beware about BGR channels ordering if you are trying to use it.
Channel order depends on platform and algorithms. All OpenCV algorithms and I/O on desktops are designed for BGR order. But on Android RBGA is used for frame capturing, drawing, conversion to bitmap and some other operations. Pay attention on it.
