Improved Algorithm for Gradient Vector Flow Based Active Contour Model Using Global and Local Information
Active contour models are used to extract object boundary from digital image, but there is poor convergence for the targets with deep concavities. We proposed an improved approach based on existing gradient vector flow methods. Main contributions of this paper are a new algorithm to determine the fa...
