Is there a difference in SNR (or any other measure of image quality) between using 2x2 pixel binning in the camera and shrinking the full resolution image in software (cv::INTER_AREA) to the same size (w/2, h/2) ?
I imagine that SNR is higher with binning if pixel binning is done "in hardware" but I'm not sure how binning is actually implemented or if it does make a difference, to what extent the difference is measurable/negligible.
