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.
