Iterative Process of Active Contours Evolving through Several Time Instants
Author: Paula Fernandes
Date: April 2008
Description: The active contour method is a semi-automatic image segmentation process based on deformable models, i.e., closed parametric curves or surfaces with physical properties that, under the influence of external and internal mechanical forces, deform and coalesce adapting to image features. This figure exhibits the active contour evolution of a cervical spine, showing a transversal section of the segmented image data (left) and the corresponding 3-D evolution (right).
