| Abstract: | 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. |
