This function PSNR = calcpsnr(f,F), will compute the PSNR of two given images. The function accepts as inputs, the 2 images where the first image is the source image f(x,y) containing N by M pixels and the second is the reconstructed image F(x,y). [note f and F must be between 0 and 255]The function also calculates the Error image by taking the difference between the reconstructed and original pixels.The typical construction of the error image multiples the difference by a constant to increase the visible difference and translates the entire image to a gray level. Formulas for these computations have been gotten fromhttp://bmrc.berkeley.edu/courseware/cs294/...nment/psnr.html onJuly 26th 2007. The code was put together by me Toritseju Okpotse same day.The code has been modified on 11-11-2008 by me, Gholamreza Anbarjafari
