I have a color image in which I want to assign/fill the background with a specific color than human faces in the same image. I create a mask by considering that the color should turn specific below a intensity limit; then use imshow. But ovelapping truns whole image balck and white. How do I fix this problem? I doubt the mask is chaged in binary. How do I convert back to RGB?
