Answer 1

[Image Analyst]

How exact do the comparisons need to be? How about subtracting them? Or use psnr or ssim? Or use SURF or CBIR methods?

[Image Analyst]

First check the sizes of all dimensions

[rows, columns, numberOfColorChannels] = size(yourImage);

if all those match up, then subtract them and look for differences

subtraction = double(image1) - double(image2);
if nnz(subtraction(:)) >= 1
  % Then they don't match
else
  % They do match
end
