pSnakes: A new radial active contour model and its application in the segmentation of the left ventricle from echocardiographic images

Highlights • To propose a new method, called pSnakes, applied and evaluated in the segmentation of the left ventricle from echocardiographic images. • To make a comparative study of methods based on active contour methods. • To apply the Hilbert transform to calculate the external energy of the prop...
