基于图象内容的链码检索方法

Conten Based on Image Chain Code Retrieval System

针对数字化图象检索问题 ,提出了一种基于图象内容的检索方法。这种检索方法是基于图象的灰度特征值 ,按照一定的分割方法 ,将图象区域化 ,并获取该区域的灰度特征描述值 ;然后把各个区域的灰度描述值按着规定的方向连接起来 ,生成一个用于检索图象的链码。实验结果表明这种基于图象内容的检索方法 ,较方便和准确地达到了图象检索之目的。

This paper discusses the question of image retrieval.A content-based image retrieval method was gave in the paper.According to the gray feature values and a definite separation method,the image is regionalised,and the gray description feature values of the image are gained.The values are chained up in a definite direction to form the so called chain code.The results indicate that the Content-based image retrieval method offers distinct advantages over some other image retrieval methods.
