Hi, I have 200 jpg images and I would like to obtain a color similarity/dissimilarity matrix between all pairs of images. I would like to use the CIElab color space as I know that it better reflects the human vision system. I know that I need to bin the color pixels of each image first and then calculate their distance. My thought was: transform the RGB to Lab first, then bin the new calculated pixels and then use the Earth Mover's Distance as a metric distance to obtain a final value for each pair. However, I am not sure if these steps are correct. Can anyone describe it step by step for me so that I can understand it better? Thank you for your help

You can use deltaE to measure the difference between colors. It works in Lab space. Check this link for more information DeltaE
