Cancate three channels to one

Question

I wanted to separate the RGB channels from the Image to perform individual operations on the one. Now I am trying to add them together. Kindly Suggest something.

Answer 1

You can just make a copy of your original image and then replace your channels with the copy using your RGB produced.

For Example:

img_cpy =img.copy()

img_cpy[:,:,0]=r

img_cpy[:,:,1]=g

img_cpy[:,:,2]=b

Make sure shapes do match.
