ABSTRACT:
A video noise reducer reduces the noise artifacts in a video signal. The video noise reducer is reconfigurable to provide spatial noise reduction and temporal noise reduction in either a parallel or cascade architecture. The video noise reducer is self-calibrating by providing estimation modules that estimate the amount of noise in the video signal and a noise injector that confirms the measurement against a known quantity of noise. The video noise reducer is adaptive to solutions in hardware or a combination of hardware and firmware. The video noise reducer is also optimized for efficient memory usage in interlaced video signal processing applications.
