直线Snakes及其在建筑物提取中的应用

Line Snake and its application in building extraction

在直线检测的基础上,将传统Snakes的基本元素由像素点变更为直线段,提出了一种直线Snakes算法.该方法利用中层图像处理技术对杂乱无章的底层图像信息的初步组织和解释功能,提高了Snakes的计算效率,增强了Snakes的稳定性鲁棒性,并在建筑物屋顶轮廓提取中提出了成功的应用.

Based on line detection, we introduce 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) for the chaotic low-level image information, the proposed method reduces the computational, reinforces the stability and robustness of snakes, and achieves a favorable performance in building extraction from aerial images.
