Efficient image stitching of an image sequence by selecting dominate frames

This paper presents an efficient image stitching algorithm with better image quality and less processing time for stitching a continuous image sequence. In the beginning, the blurred image frame is filtered out by considering the variation of its edge amount under different scales. Stitching a lot of frames with similar scene is time-consuming and easily generates the inconsistency in the overlap region between frames. In order to decrease the stitching error and the computational time, the proposed image stitching strategy desires to stitch only several significant frames instead of aligning all frames. The dominant frame with most of the visual content dissimilar to that in the previously stitched result can contribute a lot of new information and is worthy to be stitched. The proposed stitching algorithm has been verified in the on-line experiment to present the efficiency of the overall system.
