In recent decades, image segmentation based on PDE is used widely in industry. Geodesic active contour (GAC) model is a common used method. But one drawback of this model is that it's difficult to control the number of iterations and sometimes may produce an over-segmentation result. In this paper, a convergence-to-boundary method is proposed. In this method, the model combining gradient vector flow...
Geodesic active contour (GAC) model is a common used method for image segmentation. But one drawback of this model is that it's difficult to control the number of iterations and sometimes may produce over-segmentation results. In this paper, the generalized GVF in the normal direction (GNGVF) is proposed, and an improved GAC model which combines GAC with GNGVF is proposed. When the distance between...
