The performance of level set segmentation is subjected to appropriate initialization and optimal configuration of controlling parameters which require substantial manual invention. A new spatial fuzzy level set algorithm is proposed in this paper to facilitate medical image segmentation. It is able to directly evolve from initial segmentation by spatial fuzzy clustering. The controlling variabl...

Determining the minimum dominating set in connected graphs is one of most difficult problems defined as NP-hard. In this problem, it aimed to determine important nodes that can influence all via number on graph. study, an efficient near optimal algorithm showing a deterministic approach has been developed different from approximation algorithms mentioned literature for discovering set. The O(n3...

This paper is a set of notes that present the basic geometry of isosurfaces and the basic methods for using level sets to model deformable surfaces. It begins with a short introduction to isosurface geometry, including curvature. It continues with a short explanation of the level-set partial differential equations. It also presents some practical details for how to solve these equations using u...
