Support JPG comparison for the PSNR binary #339

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The psnr binary only supports YUV file comparison.
I would like to have a feature request to make psnr to support JPG comparison 
and return PSNR/SSIM values too.
Our automation relies on that binary and it will take us long(er) time to run 
if we need to convert each JPG to YUV and do the comparison.
Support JPG comparison will greatly increase the performance of our automation.
