摘要
基于形状特征的图像检索是基于内容的图像检索的一个重要的组成部分。本文介绍了小波变换应用于图像边缘检测的基本原理,并利用二次样条小波变换和Hu不变矩算法建立图像检索系统。实验结果表明,本系统具有较好的检索性能。
Shape - based image retrieval method is an important part of CBIR. This paper introduces the principle of wavelet transform applying to image edge detection. And quadratic spline wavelet and Hu invariant moments are used to implement the shape - based image retrieval in this paper. Through the experiments, it has been found that this system has good retrieval results.
