小波模极大值是在对多尺度小波变换进行不规则抽样的基础上得到的,可以用来描述信号的奇异性.提出了一种小波模极大值结合多尺度不变矩法的图像检索算法,该算法对图像进行小波变换求得多尺度下的模图像,求出所有尺度下的局部极大值及其位置,并对得到的目标边缘进行细化;采用欧氏距离来度量图像的相似性,实现图像的准确检索.同时,设计开发了一个图像检索系统,作为检索算法的测试平台.

The maximum wavelet modulus is obtained from the multi-scale wavelet transform of irregular sampling,and it can be used to describe the singularity of signals.The image retrieval algorithm,combined with Modulus maxima wavelet and the multi-scale Invariant Moments,is a method to obtain the multi-scale mode image under the wavelet transform,and all the scale of the local maxima and the location so as to obtain the multi-scale edge information,then refine it.Then use the Euclidean distance to measure the similarity to the image and achieving the accuracy of Trademark image retrieval.At the same time,a trademark image retrieval system is designed,and as test platform for a search algorithm.
