Abstract

This paper proposes a method for extracting linear object based on Freeman chain code and Hough transform with the purpose of extracting linear object effectively. After the original image is enhanced and filtered, a method based on the gray-level uniformization is used for region segmentation of image. Then the approach of Freeman chain code is carried out. Finally, the parallel linear structure is detected when Hough transform is used for the data of the chain code. The experiment results show that the proposed algorithm can extract the parallel linear structure of the image effectively, as evidenced by the fact that it showed high efficiency and high accuracy when it was applied to network target recognition in the ZY-3 satellite images.
