摘　　要：提出了一种用于图像增强的小波平滑滤波算法.该算法可根据测试图像特点改变小波变换的尺度,在区域平滑的过程中使图像的边缘锐化,较好地处理了平滑噪声和锐化边缘这对滤波技术中的矛盾.实验结果表明,该算法具有良好的滤波性能和实时性.In this paper,an algorithm of wavelets smooth filtering for enhancing the digital image is proposed. According to characteristics of the image, the scale of wavelets transformation can be changed using this algorithm therefore the edge of the image is sharpened in process of smoothing the original image.It preferably deals with the contradiction between smoothing the noise and sharpening the edge.Experiment results indicate that it performs well in filtering and real-time tasks.
