Method of and apparatus for analyzing noise in a signal processing system

摘要: A fast accurate multi-channel frequency dependent scheme for analyzing noise in a signal processing system is described herein. Noise decomposed within each channel into bands and sub-band propagated. To avoid the computational complexity of convolution, traditional methods either assume to be white, at any point pipeline, or they just ignore spatial operations. By assuming white band, it possible propagate type (white, colored, Gaussian, non-Gaussian others) across transformation very manner. demonstrate efficacy this technique, propagation considered various operations an image pipeline. Furthermore, small fraction cost propagating through system.
