小波变换在图像相关识别中的应用

Application of the wavelet transform to pattern correlation recognition

光学图像识别具有广泛的实际应用价值 ,而联合变换相关器 (JTC)是目前采用最多的一种进行图像相关识别的结构方式。将小波变换与联合变换相关技术有效地结合在一起 ,分析了如何采用小波变换来实现图像相关识别的理论方法 ,并提供了相应的结构框图 ,对采用小波变换用于图像目标识别的优点进行了概括及总结 ,并对该相关识别系统中所应采用的小波类型、滤波方式、滤波器的制作等多方面进行了介绍和分析。

Optical pattern recognition has extensive actual app li cations.The usually adopted technology is to detect the correlate intension betw een detection goal image and standard image.We combine effectively wavelet trans form with the joint transform correlator(JTC),and have analyzed how to carry ou t correlation discrimination with wavelet transform,and dedicated the theoretica l method and the structural block diagram that realizes image correlation identi fication.Finally the wavelet type,wavelet filter approach,wavelet filter perform and so on have been introduced.
