基于自适应稀疏表示的被动毫米波图像恢复
Passive millimeter wave image restoration based on adaptive sparse representation
摘要
Abstract
A novel passive millimeter wave image restoration method is proposed, which aims to overcome the shortcoming that Fourier and wavelet domain regulari- zation methods can not de-noise effectively and maintain target features simultane- ously. The new method takes advantage of sparse representation's merit of repre- senting signals flexibly. It learns from the millimeter wave image after inverse filte- ring by using K-clustering with singular value decomposition (K-SVD) algorithm to obtain basis functions adaptively for image restoration. Comparing with Fourier and wavelet domain regularization methods, the proposed method employs an adaptive method. So it can maintain target features better and de-noise more effectively, which leads to better image restoration. When the method was used in the restora- tion of simulated passive millimeter image, good result has been obtained. There- fore, it is an effective passive millimeter imaging method.关键词
