Active contour model is an effective image segmentation method,but there aren't many methods in the active contour model when determing the initial contour.In such case,this article put forward an improved skeleton extraction algorithm based active contour model to solve the problem.The model creates an initial contour by improved skeleton extraction algorithm and contour repossession algorithm,then evolves the contour towards true edge of object by the active contour model with shape energy item,to achieve the expected image segmentation.The example verification and comparision experiment prove the model can segment out the object area from the image in a much better way,with good noise immunity.Compared with traditional active contour,the model has a great improvement in segmentation accuracy.
