Abstract:
A method for measuring the amount of noise in a video image includes receiving a signal from an imaging device; extracting a luma component from a color image; applying a filter to compute the second derivatives of the extracted luma component; determining a ratio of noise pixels to total pixels in the second derivative; and comparing the ratio to a pre-determined ratio.
