Hello,
I keep getting this error:
-------------------------------------------------------------------------------------------------------------------------------------------------
??? One or more output arguments not assigned during call to "upConv".

Error in ==> reconSpyrLevs at 41
res = upConv(reshape(pyr(ind:ind+prod(res_sz)-1), res_sz(1),
res_sz(2)), ...

-------------------------------------------------------------------------------------------------------------------------------------------------

This is the code I used to call the HDR-VDP....

% Load reference and test images
R = double(hdrread( 'desk.hdr' )); % images must be
[M,N,X]= size(T)

R=R./max(R(:));
T = double(imread( 'desk004.jpg' ))/2^8; % Tone-mapped image
tt=size(T)
rr=size(R)
% Compute pixels per degree for the viewing conditions
ppd = hdrvdp_pix_per_deg( 21, [size(T,2) size(T,1)], 1 );

% Run hdrvdp
res1 = hdrvdp( T, R, 'rgb-bt.709', ppd )

Judging from the error message, you may be using a non-patched version
of matlabPyrTools. You can find a patched toolbox at:

http://sourceforge.net/apps/mediawiki/hdrvdp/index.php?title=Main_Page#Download

The second thing is that the HDR-VDP is not meant to compare HDR and
tone-mapped images. For that purpose, you want to use:

You mentioned that it is not for the purpose of comparing HDR and tone mapped. How about comparing 2 HDR images?

This should work, provided that they are calibrated in cd/m^2.
