In this paper,an efficient sequence image automatic mosaic algorithm based on phase correlation and speeded-up robust features(SURF) algorithm is proposed.Firstly,the peak value and the translation offset of the normalized cross-correlation function between adjacent images were computed and the disordered image sequence was sorted by maximal correlation degree intersecting.Then,the region of interest(ROI) was roughly computed,which improves SURF feature points extraction method and speeds up the...
