This paper proposes an improved level set method for image segmentation after analysed methods based on image grad and image region information.The new method combines image grad with image region information
which not only retains the edge-based segmentation method on the effect of edge approximation
and segmentation smooth curve
but also retains the region-based on the evolution of the segmentation method is fast
weak borders and there are empty better situation to deal with the merits of both sides.The experimental results show that the method works well and with strong robustness.
