字典学习的K-SVD算法分析

The K-SVD Analysis of Dictionary Learning

分析了字典学习的K-SVD算法,通过引入K-Means计算方法,将K-Means方法推广到用于字典学习的K-SVD计算方法中;分析和描述了K-SVD计算过程,指出了K-SVD方法与K-Means方法之间的关系,最后观察图像数据训练用于稀疏表示的字典。

The dictionary learning method i. -tended to K- means to K -SVD method e. the K through - SVD algorithm has been analyzed. We have also ex using some ideas in K - means algorithm. The K - SVD algorithm to solve real problems has been analyzed and given in detailed steps. The differences and similarities between K - SVD and K - Means have been provided. The learned dictionary has been ob- tained by theobserved image data based on the numerical experiments.
