Geometric active contour model based on signed pressure force function
Xili Wang · Journal of Computer Applications · 2012
With regard to several drawbacks of Geometric Active Contour(GAC) model,a new active contour model based on Signed Pressure Force(SPF) was proposed in this article.A region-based signed pressure force function was constructed as the edge detector in this model,which made evolving contour more sensitive to blurred edge during evolution and more robust against noise.By contrast with the traditional geometric active contour model,the proposed model has the following advantages: firstly it can segment objects with blurred boundary;secondly,it is more anti-noising;thirdly,the movement of contour is bi-directional.The experimental results show the efficiency of the proposed model.
