Abstract: An approach for extracting outline of residential area through perceptual organization and multi-scale boundaries of textured regions is presented.In the proposed approach，multi-scale edge and concept of free angle are applied to locate boundaries of residential regions，and 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 remote sensing imagery are accurate and complete.

Key words: multi-scale locating boundaries of texture region, perceptual organization, extracting outline of residential area, earial imagery
