Resumen
In this paper a DSP-based active contour model for tracking of the endocardium in a sequence of echocardiographic
images is presented. If a contour is available in the first frame of a sequence, the contours in the
subsequent frames are segmented. Deformable active contours is a technique that combine geometry, physics
and approximation theory in order to solve problems of fundamental importance to medical image analysis;
such as segmentation, representation and matching of shapes, and the tracking of objects in movement. The
procedure has been developed on a DSP processor using its hardware features. The results are illustrated using
a sequence of four-chambers apical echocardiographic images.
