CT Image Retrieval Using Tree Structured Cosine Modulated Wavelet Transform

Abstract

Developing methods for medical image characterization and indexing are in great demand for organizing and retrieving images from huge medical image databases. In this paper, novel algorithm based on tree structured cosine modulated wavelet transform (TSCMWT) for retrieval of Computer Tomography (CT) images is proposed. The proposed method performs better than existing available methods. Experimental results are promising in order to meet the requirements of the fast-paced clinical environment.
