knn for RGB images

Hello Professionals,

I have a dataset of 100 RGB images and I have to apply "KNN" with 2 classes on it. I have no idea how to do it. Please help me.

Thanks in advance

What value are you going to use for k? Can you attach your reference image with the two reference classes in it? Is there a distribution of colors in each class, or are the color regions uniform with just one, pure color in them?
