一种新的B样条主动轮廓线模型

提出了一种新的B样条主动轮廓线模型，在拉格朗日动力学方程中，文章所推导的仿射不变性模板通过弹性势能项与主动轮廓线进行实时耦合，因此新的模型对运动目标的轮廓跟踪具有仿射不变性，文章进一步讨论了控制系统的李雅普诺夫稳定性，为了有效地跟踪复杂背景中的目标，提出了一种新的特征检测方法，这一方法融合了多种图像信息，因而具有较强的鲁棒性，对真实的序列图像的实验验证了新的模型的有效性。

A New B-spline Active Contour Model

This paper proposes a new B-spline active contour model.The affine template is derived and then coupled with the active contour through the potential energy in the Lagrangian dynamics equation. Accordingly, the proposed model for visual tracking is affine invariant. Moreover, the paper discusses the stability of the control system in the sense of Lyapunov. To track objects in complex background effectively, the paper also presents a novel feature detection technique, which integrates much image information and as a result is robust for tracking in cluttered images. The experiments with real image sequences show the effectiveness of the new model.
