HDR-VDP-2: A calibrated visual metric for visibility and quality
predictions in all luminance conditions

This directory contains matlab code of the HDR-VDP-2 - a visual
difference predictor for high dynamic range images. This is the
successor of the original HDR-VDP.

Always check for the latest release of the metric at:

http://hdrvdp.sourceforge.net/

The current version number and the list of changes can be found in the
ChangeLog.txt.

-----------------------------------------------------------------
To install the metric just add the hdrvdp directory to the matlab path. 

HDR-VDP-2 requres matlabPyrTools (http://www.cns.nyu.edu/~lcv/software.html).
The first invocation of the hdrvdp() function will add matlabPyrTools 
automatically to the matlab path. If you already have matlabPyrTools in 
the path, the metric may fail, as HDR-VDP-2 requires a patched version of 
that toolbox. 


-----------------------------------------------------------------
To run the metric:

Check Contents.m and the documentation for hdrvdp.m,
hdrvdp_visualize.m and hdrvdp_pix_per_deg.m
