一种适于图像细节保持的全方位多级组合滤波器

A CLASS OF EFFECTIVE IMAGE DETAIL PRESERVING FILTERS ——OMNIDIRECTIONAL MULTISTAGE COMBINATION FILTERS

本文在传统滤波器的基础上，结合全方位多结构元，提出了一种有效保持图像细节的滤波器——全方位多级组合滤波器．它能针对不同图像区域自动选取不同的滤波单元，充分发挥各级滤波单元的优点．图像处理仿真实验表明，在滤除噪声和保持图像细节方面，具有较好的效果．

Based on traditional filters and omnidirectional multiple structuring elements, a class of effective image detail preserving filters——omnidirectional multistage combination filters——are proposed in this paper. In the design stage of these filters, different filter units can be chosen automatically in accordance with different image regions, so that all kinds of filter units can be used effectively. A standard test image is filtered in noisy environment. The results of simulation show that the new filter performs better in noise suppressing and detail preserving.
