What is peak of signal?

PSNR is defined as the ratio of the maximum possible power of a signal to the power of corrupting noise that affects representation fidelity.

How do you find peak to peak in Matlab?

y = peak2peak( x ) returns the difference between the maximum and minimum values in x . y = peak2peak( x , dim ) computes the maximum-to-minimum differences of x along dimension dim .

What is peak detection algorithm?

A new automatic peak detection algorithm is developed and applied to histogram-based image data reduction (quantization). The algorithm uses a peak detection signal derived either from the image histogram or the cumulative distribution function to locate the peaks in the image histogram.
