Error in compute_difference.m: unknown variable/function 'warpedImage'

[pputzky]

Hi,

First of all, thank you for the excellent work and code! I was trying to evaluate my own method with you quantification script. But there seems to be an error in the function compute_difference.m

At some point in the code the function tries to use variable warpedImage:

% Compute Structural similarity index (SSIM index)
45	% =========================================================================
46	[ssim, ~] = ssim_index(imgt, warpedImage);
…	
49	% Compute information fidelity criterion (IFC)
50	% =========================================================================
51	ifc = ifcvec(imgt, warpedImage);

But warpedImage was not defined before. I am guessing it should just be replaced with 'im' such that the code becomes

% Compute Structural similarity index (SSIM index)
45	% =========================================================================
46	[ssim, ~] = ssim_index(imgt, im);
…	
49	% Compute information fidelity criterion (IFC)
50	% =========================================================================
51	ifc = ifcvec(imgt, im);

Is this correct, or did you intend to have another preprocessing step which produces warpedImage?

Thanks again for the great work!

Cheers
