摘要
SNAKE模型主要应用在医学图像,运动跟踪,形状识别等领域.文中阐述了在视频摄像中运动物体轮廓跟踪的方法及其改进算法.首先由用户在感兴趣的物体附近指定其初始轮廓,随后该轮廓曲线会进化并锁住物体的边缘.一旦初始轮廓获得之后,后继帧中该物体的运动轨迹即可被跟踪且不需要用户再输入任何参数.
SNAKE model is mostly applied in medical image manipulation, motion track, shape recognition, and so on. An approach in tracking moving objects in video frequency is proposed and modified in this paper. Firstly, an initial contour line will be appointed close to the object interested. Then the contour line will be evolved and the object edge will be locked. When the initial contour line of the object is obtained,its motion should be tracked in subsequent frames without any input parameter from user.
