Hi All,

I am developing an AOI system using OpenCV and thought of using DCT for the illumination normalization of the input images.

Can anyone please tell me what is the strategy that should be used when removing DCT coeficients or downscaling DCT coeficients? Thanks.

i hope initially coefficients are in 8 bit,

first multiply each coefficients with 2048, before any processing and convert them to an integer, then do your processing after that divide each process data by 2048.
