A New Two-Step Method for Medical Image Retrieval

Abstract

In this paper, authors propose a new two-step medical image retrieval method which combines cooccurrence matrix texture feature and gradient phase mutual information(GP_MI). The new method provides fast retrieval respond speed while achieves high precision and good robustness in retrieval process. Experimental results show that the algorithm has potential practical values for clinical routine application.
