并行多分辨率子波变换(WT)及其实现方法研究2.在目标轮廓抽取中的应用

Parallel Multiresolution Wavelet Transform(WT) and its Application

子波变换的局域分析特性使它可用于目标阶跃边缘的增强，达到抽取目标轮廓特征的目的。本文中介绍了采用光学及数字方法实现子波变换，抽取目标边缘的理论及实验结果，并通过比较看出。

The local analysis property of wavelet transform is appled in object edge enhancement to extract the edge feature.In this paper,the experimental results of wavelet transform are introduced.Making a comparison,we can conclude that the digital method is better than the optical method in implementing wavelet transform.
