title: Plot of mean square error [EDIT]
body: <p>If this be the formula for MSE for RGB images A,B of same size 256*200, then how to obtain a line plot for every pixel with x axis representing pixels and y axis representing the MSE values </p>
  
  <p>MSE = reshape(mean(mean((double(A) - double(B)).^2,2),1),[1,3])</p>
  
  <p>There are only two images A ,B. The plot should illustrate change between each pixel of A and B which is meant by MSE.</p>
