Hello,
“opencv rgb to gray custom” Code Answer’s. Bgr2gray opencv. Whatever by Hilarious Hamerkop on Apr 30 2020 Donate. Cv2 turn rgb image to grayscale. And as you see, the conversion back to color is only adding the gray scale value to the 3 channels of colors RGB. Why do we lose information? The key to understand is that a color image has three channels for each pixel, while a gray scale image only has one channel.
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 :-)
