Title: Video foreground segmentation with camera movement
Abstract: A new approach based on non-parametric motion estimation and image registration was proposed for video foreground segmentation with camera movement.First,non-parametric motion estimation was conducted between the video frame containing foreground and a similar training background image.Then,a new background image with exactly the same viewpoint as the video frame was constructed on the fly,and foreground pixels were segmented by classical background subtraction.A manifold based extension was also proposed to alleviate the low efficiency of motion estimation.In the offline stage,motion estimation for training background images was pre-calculated,and a low-dimensional background manifold was discovered.In the online stage,motion estimation involving the new frame was conducted by fast interpolation on the manifold.Experimental results show that the proposed method segments videos accurately and efficiently.
