Abstract: In this paper, the nature of the PLS algorithm is analyzed. To overcome its disadvantages, a modified PLS algorithm is proposed. Experimental results are presented to provide synthetic data and real image sequences. Compared with PLS and EKF algorithm, the modified algorithm can estimate motion more accurately in real-time.
