摘　　要：提出了一种基于Snake模型的改进算法,不仅能够精确地搜索到图像轮廓,且程序运行速度较快。该算法在CMU数据库上进行了实验,结果表明提取出的步态轮廓完整且封闭,能有效地提高识别率。A gait contour extraction method based on Snake model was proposed, which can search the contour not only correctly but also rapidly. The experiments tested on the CMU database prove that the gait contour can be completely and closely extracted by the proposed method, and recognition rate is also increased effectively.
