基于纹理边缘与感知编组的居民地外轮廓提取

Extracting Outline of Residential Area Using the Perceptual Organization and Boundaries of Textured Regions

提出了一种在高分辨率遥感影像上提取居民地外轮廓的方法。该方法通过计算边缘点的角度提取居民地外轮廓,并利用感知编组连接提取轮廓点,形成闭合外轮廓。实验证明,本方法提取居民地外轮廓位置准确且完整闭合。

An approach for extracting outline of residential area through perceptual organization and boundaries of textured regions is presented. In the proposed approach, the concept of free angle is applied to locate boundaries of residential regions. Then multiple clues are integrated into the procedure of curve perceptual organization to obtain close and long boundary. Experimental results show that extracted boundaries of residential area from high resolution remote sensing imagery are accurate and complete.
