Cong Liu · Jisuanji gongcheng yu sheji · 2010
In order to improve the retrieval accuracy in image retrieval system for hospital medical image, the content-based image retrieval method is studied comprehensive. The advantages of wavelet transform and run-length matrix in image retrieval are analyzzed deeply. A algorithm with wavelet decomposition and the run-length matrix is proposed. It make full use of the advantages of multiscale analysis, as well as the advantages of run-length matrix can be described within the gray-scale images. And use Gaussian distribution to the wavelet decomposition scale image after run-length matrix features integration reasonable. And simulation algorithms and other algorithms are compared, the result show that the method effectively improve the accuracy of image retrieval.
