摘　　要：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。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.
