Improved Method of Distance Regularized Level Set Evolution

To effectively extract the outline of objects in the image,a modified distance regularized level set evolution(V-DRLSE) was presented.First,the initial contour was obtained by the saliency map of visual attention mechanisms,which was no longer sensitive to the position and could expand in the level set evolution.Second,a new edge indicator function was defined,which could speed up the curve evolution by optimizing parameters.Finally,the object boundaries were acquired using distance regularized level set evolution.The simulation experiment results on images of different characteristics show that it can detect boundary of single object or boundaries of multi-objects and position accurately.It also has strong anti-noise ability.
