梯度矢量流与测地线活动轮廓混合模型的存在唯一性
Existence and uniqueness results for the Gradient Vector Flow and geodesic active contours mixed model
摘要:
本文介绍了C.徐俊龙王子我们给出了存在性和唯一性的边界提取,是由Paragios,Mellina-Gottardo等Ralmesh的前传播流的结果。该模型结合测地线活动轮廓流和GVF来确定几何流。运动方程被认为是一个水平集公式,从而产生一个哈密尔顿-雅可比方程。
英文摘要:
This article deals with the so called GVF (Gradient Vector Flow) introduced by C. Xu, J.L. Prince . We give existence and uniqueness results for the front propagation flow for boundary extraction that was initiated by Paragios, Mellina-Gottardo et Ralmesh . The model combines the geodesic active contour flow and the GVF to determine the geometric flow. The motion equation is considered within a level set formulation to result an Hamilton-Jacobi equation.
