| 摘 要： | 为了使图像既能去除噪声又获得增强,基于平滑低通滤波器、中值滤波器去除图像噪声原理和改进的巴特沃斯高通滤波器的图像对比度增强与边缘保持的原理,提出了一种新的均值去噪与图像增强的方差滤波器.实验结果表明,该方差滤波器无论在噪声去除、对比度增强、边缘保持等方面都优于上述3种滤波器.

| Abstract: | Based on image denoising principles of smoothed low pass filter,median filter and improved butterworth high pass filter,a new variance filter was brought up,and the principle of denoising and image enhancement was analyzed in detailed.The result of experiment verify that the new filter is better in denoising and image enhancement than the above three filters. |
