  • System and method for video quality parametric tests
    Patent number: 8730327
    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.

  • System and method for video quality parametric tests
    Patent number: 8310548
    Abstract: A method and system for automatically evaluating the quality of a signal transmitted by an imaging device. The amount of noise in the video signal is analyzed using an algorithm that does not require comparison to a template signal. The results of the algorithm determine whether the signal meets a pre-determined threshold value for signal quality.
