摘要
Abstract
The phase quality map of phase derivative variance is reliable .When the size of computing window is larger , the computing efficiency is too low ,which affects the speed of signal processing .A fast computing method for phase deriva‐tive variance is proposed in this paper ,which uses multi‐computing cores to compute the phase quality map for every blocked wrapped phase .Then the result is downloaded to the memory of host .At last ,the high efficiency of the proposed method is verified through experiment .关键词
