First of starting image processing whether on gray scale or color images, it is better to focus on the applications which we are applying. Unless and otherwise, if we choose one of them randomly, it will create accuracy problem in our result.

Because in the bin image I want only to detect the shape of bin image using optimized edge detection. I could not bother about the color of image but I want to see rectangular shape of the bin image correctly.
