Psnr Calculation In Matlab For Mac
PSNR can be calculated for the two image, one is input image and another ones in noisy affected image. You can try with the example. A = image1; B = image2; C = psnr (A,B) A is input image, B is noisy image, from this we can have a signal to noise ration result. The PSNR is calculated by using following formula. MAXI=Maximum value of pixel in Original image. Of Row in Original image. Of Column in Original image. Procedure: 1. Read Original Image from current directory. Read Noisy Image from current directory.
