| Abstract: | 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. |
