| 摘 要： | 提出一种新的广泛应用于数字图象分析和计算机视觉的主动轮廓(Snake)模型,引入作用方向可以自适应变化的外加强制力,使控制点能够不依赖于初始轮廓而快速地收敛到目标的真实轮廓;初始轮廓自动确定;控制点的数目可以自适应地改变;能够在背景比较复杂的图象中实现对目标轮廓的提取.用该模型对空中目标的红外图象进行的实验结果表明其具有很好的鲁棒性和实用性.

| Abstract: | Active contour model("Stake") has been widely used in application of digital image analysis and computer vision.In this paper,a new active contour model--"Auto Snake" is proposed.Adaptive hard constrain is introduced,so controlling points of Snake undepend on the position of original contour,and the Snake converges on real edge of object quickly.The original position of Snake is automatically obtained.The number of controlling points of Snake can be changed adaptively.And contour of object also can be gotten in some complex background.Experiment results for infrared images of aerial objects demonstrate the robustness and practicality of this algorithm. |
