小波分析在磁光记录薄膜磁畴图象处理中的应用

摘要

Characteristics of wavelet were briefly introduced． The two-dimensional discrete wavelet transform algorithm of image and edge detection algorithm based on wavelet were analyzed． Wavelet analysis was used on magnetic domain images of magneto-optical films to realize such funcions as image enhancement， image denoise， edge detection， et al． The image of magnetic domain was analyzed and the characteristic parameters exactly calculated．%简单介绍了小波分析的特点，分析了图象的二维离散小波变换算法和基于小波的边缘检测算法，采用小波分析对磁畴图象进行了图象增强、图象消噪及边缘检测等处理，较好地分析了磁畴的图象，准确地计算了磁畴的特性参数。
