pSnakes: A new radial active contour model and its application in the segmentation of the left ventricle from echocardiographic images
Active contours are image segmentation methods that minimize the total energy of the
contour to be segmented. Among the active contour methods, the radial methods have lower
computational complexity and can be applied in real time. This work aims to present a new
radial active contour technique, called pSnakes, using the 1D Hilbert transform as external
energy. The pSnakes method is based on the fact that the beams in ultrasound equipment
diverge from a single point of the probe, thus enabling the use of polar coordinates in the …
