Abstract: This paper presented an optimized algorithm of frame selection on the stitching of videos with overlapped visions. Firstly，it compared the Scale Invariant Feature Transform (SIFT) value differences of all the match points of standard frame and candidacy frames, and then selected the point pairs with minimal SIFT value difference, and calculated the mean values of these differences. Finally, the frame with the minimum mean value was selected as the best frame, and stitched with the standard frame. This algorithm assures the best matching frame and can be used to choose the best stitching frame automatically in video stitching. Simulation shows the effectiveness of this algorithm.
