Active contour model and nonlinear shape priors with application to left ventricle segmentation in cardiac MR images

This paper presents a new active contour model for left ventricle segmentation in cardiac magnetic resonance (MR) images. In this study, the shape prior is coupled with intensity information in the proposed energy functional which includes a data term and a shape term. The data term, inspired from a region-based active contour model, is used to guide the motion of the initial curve to desired object boundaries. Meanwhile, the shape term is...
