An Improved Model of Snakes for Model-Based Segmentation

摘要: The main advantage of segmentation by snakes consists in its ability to incorporate smoothness constraints on the detected shapes that can occur. Likewise, we propose model with other properties reflect information provided about object interest a different extent. We consider kinds snakes, those searching for contours certain direction, preserving an object's model, seeking symmetry, expanding open, etc. availability such collection allows not only more complete use knowledge segmented object, but also solve some problems existing snakes. Our experiments facial features justify usefulness properties.
