随着数字图象技术、宽带网络技术和数字存储设备技术的发展，在网络上存储、传输大规模分布式数字图象库 成为可能，因此研究基于内容的图象检索技术成为近几年的热点。实现基于内容的图象检索系统的关键问题是实现图象 的语义分割。该文分六类对现有的图象语义分割技术进行了全面的总结，为进一步研究基于内容的图象检索技术奠定了 基础。-With the digital image technology, broadband networks and digital storage device tech

The colors features based on overall histogram neglecting images’ spacial information may be imprecise in image retrieval, since different image may has same histogram. Two color features with special information based on image fixed segmenta

cbirIn this paper, we present a new framework for effective content-based image retrieval (CBIR) using rectangular segmentation. In image segmentation, speed is more important than accuracy in CBIR. We propose a new rectangular approximate image segm
