Converting `BufferedImage` to `Mat` in OpenCV

by

I also was trying to do the same thing, because of need to combining image processed with two libraries. And what I’ve tried to do is to put byte[] in to Mat instead of RGB value. And it worked! So what I did was:

1.Converted BufferedImage to byte array with:

byte[] pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();

2. Then you can simply put it to Mat if you set type to CV_8UC3

image_final.put(0, 0, pixels);

Edit:
Also you can try to do the inverse as on this answer
