PSNR-HMA download page

PSNR-HMA is Peak Signal to Noise Ratio taking into account Contrast Sensitivity Function (CSF), between-coefficient contrast masking of DCT basis functions as well as mean shift and contrast changing.

PSNR-HA is the same metric without taking into account constrast masking.

Descriptions of PSNR-HMA and PSNR-HA are given in following paper:
