| 摘 要： | 利用光学中的阶跃滤波器实现对多灰度级图像的区域分割，并从理论上对用阶跃滤波器处理具有硬边界和软边界的多灰度级图像及最终实现多灰度级图像的区域分割进行了讨论。当多灰度级图像存在灰度不连续变化(硬边界)和有转折变化(尖点)时，使用阶跃滤波器都会在这样的区域内呈现边界增强。 |
| 关 键 词： | 多灰度图像 阶跃滤波器 区域分割 图像处理 |

| Abstract: | In this paper,the region splitting of multi-gray level picture is directly brought about with a optical step filter. It is discussed in theory that a step filter processes a multi-gray picture with hard and soft boundaries to realize the region splitting of the multi-gray level picture. The discussion shows that with the step filter. The boundary enhancement in the region will appear when the noncontinuous gray grade (a hard boundary) and the epoch emerge in the multi-gray picture . |
| Keywords: | multi-gray level picture step filter region splitting image processing |
