Watershed-Presegmented Snake for Boundary Detection and Tracking of Left Ventricle in Echocardiographic Images

Abstract

In this paper, an automated method of boundary detection of the left ventricle (LV) is proposed. The method uses a watershed transform and morphological operation to locate the region containing the LV, then performs snake deformation with a multiscale directional edge map for the detection of the endocardial boundary of the LV.
