MSU Brightness Independent PSNR Plugin for MSU Video Quality Measurement Tool. MSU Brightness Independent PSNR Plugin will allow you to compare codecs correctly, even if one of them have changed average brightness of the frame.

BI-PSNR metric should be used when one of the sequences has any brightness transformation, which does not change within frame. Example of such transformation is uniform increasing of brightness of contrast for single frame of for all sequence.

Such transformations prevent usage of standard metrics because of strong brightness difference between comparing frames. BI-PSNR algorithm calculates brightness transformation, which makes frames similar as possible and calculates standard PSNR and MSE metrics taking into account founded transformation.
