Abstract :
This paper presents a novel motion parameter estimation algorithm based on the multiresolution edge detection. First, moving object edges is detected based on wavelet transform between two consecutive frames. Then, edges location of moving objects is generated through multiresolution relevant operator. Finally, moving object vector fields is detected according to its edge location. Based on the edge detection method not only the intraframe intensity information of spatial domain is used, but also the interframe information in temporal domain. Experimental results show that the proposed algorithm is effective with robustness.
