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.
摘要
本文提出了一种自动检测左心室（LV）边界的方法。该方法利用分水岭变换和形态学操作来定位包含左心室的区域，然后使用多尺度方向边缘图进行蛇形变形，以检测左心室的心内膜边界。
