Abstract:

In recent years, we can pick up important information from images with the proposed independent components analysis (ICA) algorithm based on non-Gaussian distribution metric. In this paper , The ICA filters were obtained by MIT image dataset based on FastICA algorithm, by this algorithm , the sampling of image pitches from different scenes can be obtained by constructing a training sets based on one scene, and the results of each group of ICA filters were obtained and analyzed. The experiments indicated that ICA filtering can gain sparse code of different scenes images, and it has adaptive characters to training sets.

Key words: image filtering, adaptive filtering, independent components analysis,  sparse encode
