| 摘 要： | 本文首先介绍了小波域中几种常用的滤波方法,分析了双边滤波的性质和特点,在此基础上提出了小波域中的双边滤波.这种方法充分利用了小波分析的时频局部化和多分辨率的特点,使滤波结果的信噪比较高的同时边缘具有较小的模糊.本文的实验结果说明该方法是行之有效的.

| Abstract: | In this paper,we introduced several noise removing techniques in the wavelet domain,analyzed the properties of bilateral filtering.Following them,bilateral filtering in the wavelet domain was proposed.With this method,the properties of time-frequency localization and multiresolution of wavelets were used.At last,we demonstrated the efficient noise removing and sharpening of object boundaries and detailed structures by applying this image processing technique to different images. |
