A new active contour remote sensing river image segmentation algorithm inspired from the cross entropy

- A new active contour image segmentation model is proposed in this paper which measures the cross entropy of the given image and the segmented image.
- A level set implementation of the new active model is proposed and a distance regularized term is added to the objective functional.
- A fast global minimization of the new active model is proposed, and the implementation speed of this formulation is fast.
