| 摘要: |
| 为了在图像去噪处理中更好地保持或还原图像细节,针对脉冲噪声,把滤波窗口中等值的像素压缩后作自适应中值滤波,提出基于同值压缩的自适应中值滤波算法,并用实验来检测其优越性.该滤波算法执行速度快,去噪性能和图像细节保持及还原能力明显优于经典中值滤波及自适应中值滤波. |

| Abstract: |
| In order to maintain or restore image detail better in the Image Denoising treatment,and in view of impulse noise filtering,in this article the pixels of equivalent value was compressed and got its median value in the filter window.And bring up adaptive median filter which based on equivalent values compressing,proposed for images corrupted with pepper and salt noise.The test results showed that it processed faster,denoising performance,maintain and restore image detail capability are obviously superior to the classic median filter and adaptive median filter. |
| Key words: median filter impulse noise equivalent value compression adaptive |
