Robust Video Mosaicing with Block Matching Method
Zhongxin Li · 2006
A robust image mosaic method is proposed to construct a panoramic view of the scene from video sequence.Firstly,block matching method based on phase correlation is employed to estimate the motion vector field of video frames.After removing the outlier motion vector caused by the image noise or moving object occlusion,the corresponding point pairs between image blocks can be determined by the dominant motion vectors,and then the parameters of projective transformation model can be iteratively estimated with the obtained correspondences to implement the video mosaicing.All the work of video mosaicing is automatically completed without manual manipulation.Experimental results using video sequence with real scene have demonstrated the availability of the method.
