This challenge is to score the image Similarity given the Goal.png as an [m,n,3] matrix,G, and a Submit.png matrix,S.
A video of FrictionlessBananasSawicki paint steps, [2FBS.mp4.avi] shows the processing method to create Submit.png.
ImgScore = round(alpha * sum(pixel_distances)) with alpha=0.005 where pixel_distance = (rdist+gdist+bdist)^0.5
where rdist=(G(X,Y,1)-S(X,Y,1))^2, gdist=(G(X,Y,2)-S(X,Y,2))^2, bdist=(G(X,Y,3)-S(X,Y,3))^2
