Image Stitching Based on Motion Estimation

To get the scene image of wide view field, firstly block matching based on phase correlation is applied to estimate the motion vector field, then the outlier motion vectors caused by image noise or shadow of motion object are rejected with the motion vector distribution, lastly the parameters of transformation model can be calculated with the obtained dominant motion vectors to implement image sequence stitching. Experimental result using real image sequence demonstrates the availability of this method.
