| 摘 要： | 边缘信息是地物间波谱差异的反映.仅仅考虑灰度差异并不能满足专题信息-地物边缘提取的需要.加入地物的空间形态特征依据,可以使边缘信息提取更准确.在灰值形态学梯度算法和多方位形态结构元素形态学理论分析基础上,提出了提取遥感图像边缘信息的新方法.叙述了结构元素的设计和边缘提取过程,给出了应用实例并得到良好的视觉效果.

| Abstract: | Boundary information is the reflection of the spectral difference between objects. Only considering the gray value of objects is not sufficient to extract the thematic information-objects boundary. The combination of the gray value and the objects shape information will greatly promote the accuracy of the extraction. Based on morphology grads algorithms and multi-direction morphology structure element of mathematical morphology theory, this paper presents a new method for remote sensing image edge detection. The design of structure element and the processing of edge detection are described in detail and some examples are also showed. |
