Hello,
I have a grayscale image (CV_8UC1) and I use findContours to identify contours. These contours I would like to draw colored into the grayscale image.
I tried to merge two empty Mats(CV_8UC1) together with the grayscale image and this works not really well. So I have my wished colors, but the original image is blue, red or green depending on the merged channel position.
How can I achieve the grayscale image staying gray with having colored contoures on top?
Thank you very much :-)
