-This paper describes an improved segmentation algorithm based on Minimum Spanning Tree (MST) for content-based image retrieval system. MST segmentation is computationally efficient and captures both global and local image information, but it is prone to incur over-segmentation because of its neighbor system. To address this problem, an adaptive neighbor mode in the improved segmentation is defined...
With the rapid increase of the medical images and the wide application of PACS, more and more attention is paid to the effective lossless compression of the medical images. In this paper, a compression method compatible with JPEG-LS standard and based on neighborhood's match is presented. A context vector predictive model is used to remove the redundancy of the neighborhood pixels. The experimental...
