N2 - In this paper, we propose a new automatic tracking method for 2-D motion of Regional myocardial motion in high-frame rate echocardiography by using the correlation method with connective multiple ROIs. Several automatic tracking methods by means of correlation method and image gradient method are proposed. However, these method tend to fail to track the motion of object because of a considerable speckle noise contained in echocardiography. The proposed method in this paper is a combination method of maximization for correlation of brightness distribution and optimization the geometric location of ROIs. We compared tracking accuracies of conventional method and proposed method in evaluation test. Results of these tests shows that proposed method is able to derive more accurate trajectories from echocardiography than conventional method.
