calcpsnr

25 Nov 2008

A simple function to find PSNR between two images!

File Information

Description

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 from
