Application of Blind-Signal-Processing Algorithm in Image Separation - Blind-Signal-Processing in Image Separation

Abstract

We take advantage of the relative gradient method and the bound component analysis algorithm to propose the relativegradient bound component analysis algorithm in this paper. This algorithm does not need to compute the inverse matrix and the covariance matrix. It can succesfully separate the mixed pictures without whitening. The time complexity and the space complexity of this algorithm are both lower than those of the original bound component analysis algorithm.
