Abstract

Abstract: Based on line detection, we i
ntroduce a line snake algorithm with vertices of traditional snakes replaced by
straight line exemplars. Through the preliminary organization and interpretation
functions of middle-level image processing techniques (e.g., line detection) f
or the chaotic low-level image information, the proposed method reduces the com
putational, reinforces the stability and robustness of snakes, and achieves a fa
vorable performance in building extraction from aerial images.

Key words: straight lines snakes, building extraction, image information
