Directionally weakened diffusion for image segmentation using active contours

Directionally weakened diffusion for image segmentation using active contours

The active contour model, also known as the snake model, is an elegant approach for image segmentation and motion tracking. The gradient vector flow (GVF) is an effective external force for active contours. However, the GVF model is based on isotropic diffusion and does not take the image structure...
