Watershed-Presegmented Snake for Boundary Detection and Tracking of Left Ventricle in Echocardiographic Images
Jing Cheng, Say Wei Foo, S.M. Krishnan · IEEE Transactions on Information Technology in Biomedicine · 2006
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.
