基于结构相似性的非参数贝叶斯字典学习算法
Nonparametric Bayesian dictionary learning algorithm based on structural similarity
摘要
Abstract
Though nonparametric Bayesian methods possesses significant superiority with respect to traditional comprehensive dictionary learning methods, there is room for improvement of this method as it needs more consideration over the structural similarity and variability of images. To solve this problem, a nonparametric Bayesian dictionary learning algorithm based on structural similarity was proposed. The algorithm improved the structural representing ability of dictionaries by clustering images according to their non-local structural similarity and introducing block structure into sparse representing of images. Denoising and compressed sensing experiments showed that the proposed algorithm performs better than several current popular unsupervised dictionary learning algorithms.关键词
