Abstract
The technology of medical image retrieval in picture archiving and communication systems (PACS) is of great importance. A shape prior algorithm retrieval based on interest point is presented in this paper. Firstly, according to the formulaic composition of a medical image, a Harris point detector is improved to extract some interest points in images. Secondly, by combining invariants for each point and an edge type histogram, the feature vector for matching is constructed. Finally, a strategy for matching vectors is implemented to retrieve medical images. The test results prove the efficiency of this approach.
