From the help of the Image Processing Toolbox:
psnr
Peak Signal-to-Noise Ratio (PSNR) expand all in page
Syntax
peaksnr = psnr(A,ref)example
peaksnr = psnr(A,ref,peakval)
[peaksnr,snr] = psnr(___)
Description
example
peaksnr = psnr(A,ref) calculates the peak signal-to-noise ratio for the image A, with the image ref as the reference. A and ref must be of the same size and class.
peaksnr = psnr(A,ref,peakval) uses peakval as the peak signal value for calculating the peak signal-to-noise ratio for image A.
[peaksnr,snr] = psnr(___) returns the simple signal-to-noise ratio, snr, in addition to the peak signal-to-noise ratio.
