基于 3D,录像为多目标分割被建议并且与一个动人的看系统追踪的一个方法。一个空间与时间的精力功能被建立同时执行运动分割和评价。与水平集合方法克服本地最小的问题的限制,一个凸的松驰方法被用于 3D 空间与时间的分割模型。放松的凸的模型独立于起始的条件。一个最初双的算法被用来改进计算效率。几个室内的实验显示出建议方法的有效性。
A method based on 3D videos is proposed for multi-target segmentation and tracking with a moving viewing system. A spatiotemporal energy functional is built up to perform motion segmentation and estimation simultaneously. To overcome the limitation of the local minimum problem with the level set method, a convex relaxation method is applied to the 3 D spatiotemporal segmentation model. The relaxed convex model is independent of the initial condition. A primal-dual algorithm is used to improve computational efficiency. Several indoor experiments show the validity of the proposed method.
