This paper presents a parallel processing method of decorrelation stretching with multiple decomposition tactics for remotely sensed imagery.The method adopts different decomposition tactics for different steps in the whole procedure with band-based decomposition in the statistics of image bands,twin-band-based decomposition in the computation of the covariance matrix,and tile-based decomposition in the linear transformation.The whole procedure is parallelized.The parallel experiments of decorrelation stret...
