| 摘 要： | 根据脉冲噪声和高斯噪声在小波变换下的不同特点,结合中值滤波,在小波域内对高频子带图像进行中值滤波.仿真结果表明,此算法不仅能滤除图像中的脉冲噪声和高斯噪声,且能较好的保留图像的边缘细节,可获得较好的去噪效果.

| Abstract: | In this study, the different characteristics of impulse and Gaussian noises under the condition of wavelet transform are addressed. Median filtering is applied to the high-frequency sub-band images within the wavelet domain. Simulation result shows that this method is effec- tive in removing the impulse and Gaussian noises in the images, as well as in preserving a good edge detail of the images, hence, a good de-noising effect. |
