An Optical Flow-Based PIG Method for Active Contour Tracking Initialization

摘要：

　　In this paper,we propose a new optical flow-based Poisson inverse gradient (OFPIG) initialization method for active contour tracking.This method can automatically initialize the contour of moving target for consequent tracking.First,an optical flow based motion detection method is adopted to remove background information,and then a Poisson inverse gradient (PIG) initialization is applied to locate the target region.Finally,parametric active contour is used to evolve the correct target contour depending on the initialization precision.Experimental results have demonstrated its effectiveness and robustness.
