This research studies the Discrete Cosine Transform Based Gradient Vector Flow in Normal Direction (DCT based NGVF) Active Contours in comparison with the Discrete Cosine Transform Based Gradient Vector Flow (DCT based GVF) Active Contours. Extensive research has been done on DCT based GVF Active Contours and the strengths of DCT based GVF Active Contours have been established. NGVF, the recent improvement to the GVF Active Contour has faster convergence speed towards the concavity and bigger time step. It also has the capability to enter into long, thin indention and provide a good contour. The DCT based NGVF Active Contours has the combined strengths of the NGVF Active Contours and the DCT based GVF Active Contour formulation. This research experimentally studies the merit of the DCT based NGVF Active Contours in comparison with the DCT based GVF Active Contours. The experimental inferences shed more light on the comparative merits of DCT based NGVF Active Contours. |
