Abstract

A gradient-based method is applied to analyze two echocardiograph sequence velocity field. The method assumes local spatial constancy of the optical flow and uses a weighted least-squares minimization to determine the optical flow. A hierarchical improvement to the method is proposed to solve the problems of motion blur and sensitivity to noise. Experimental results show that both the implemented method and the improvement to it are available to obtain global quality evaluation of the velocity field of the echocardiograph sequences
