GLOBAL MEASURE ON IMAGE CONTENT

IntroductionContent- based image retrieval has been proposedto allow retrieval to be performed on the basis ofa variety of aspects of image content[1] .A chal-lenging problem arises with many imagedatabases,within which queries are posed via vi-sual or pictorial examples.A common visualquery to an image database system would involvefinding all images in the database which containa subimage that is similar to the query image.Such retrievals must be based on embedded con-tent features,such as sh…     

一种求取三角网格参数化域的方法

这是把多分辨率分析推广到任意类型且不具有细分连续性的三角网格分解、压缩及重构中去的一个过渡步骤，要将多分辨分析应用到三角网格分解、压缩及重构当中，首先解决的问题应是三角网格的参数化，即把三角网格定义为某个域上的函数。作为参数化的第一步，本文利用Voronoi图的分块技术求取参数化域。本方法已在SGIIndigo2上得以实现。     

一种非平移不变域上紧支撑小波的构造方法

本文以一个简单的非平移不变域为实例进行多分辨分析，在其上构造紧支撑小波，并试图通过对在实线段域上构造小波基的过程作解释和证明，以便蒋其思想应用到其它非平移不变拓扑域上。
