When an image contour is judged by virtue of the method, local characteristics under a plurality of channels of the image and global characteristics among pixels of the image are combined, so that the obtained

An active contour method using AMF for the update of the level-set functions is the following AAC algorithm: AAC Algorithm 1. For all pixels i, compute amoeba-structuring elements Ai from the input image f. 2. For the given initial contour, construct the level-set function u(0) as signed...

The algorithm's parameters, such as edge attraction, internal elasticity, and user-defined constraints, can be adjusted to achieve accurate segmentation results. The Active Contour Model is widely used in medical imaging, object tracking, and computer vision applications due to its ability to ...
, and propose a novel version of TLS-ESPRIT based on higher-order statistics for correlated noise environment. Then, we derive a least-squares criterion and propose an alternating least-squares algorithm to retrieve simultaneously all spread values of concentric circles. Experiments performed on hand-...
By using an edge detector algorithm we can trace the main edges of an image and animate them. The generated SVG is composed of multiplepolylines, which are animated using JS and CSS. The resulting SVG is so small (in the order of a handful kBs) that can be inlined in the HTML and ...
A classical simulated annealing algorithm is used. A Boltzmann distribution [43] is assumed and, consequently, a logarithmic cooling schedule is used. This method initially considers the generation of a contour in the 2-D image space having a given number of vertices. A neighborhood patch of n...
