opencv - Is it possible to make two grayscale images stastistically equivalent? -

-

i have 2 grayscale images g1 , g2 . have statistics (min ,max ,mean , standard deviation). change g2 such statistics of g2 (min ,max,mean , sd)match g1. have tried arithmetic scaling , got min , max values of both g1 , g2 match mean , sd still different. have tried histogram fitting of g2 in g1 did not wanted either. using software called spider question applicable image-processing can performed using different software packages(opencv matlabetc) .any ideas , suggestions appreciated.

the easiest thing apply histogram equalization both images (histeq in matlab). if not want change both images, can histogram matching, that's bit more complicated.
