[Special Effects] snake DL : 0: Snake 算法或Active Contour Models。这类算法需要给出初始的轮廓，然后进行迭代，使轮廓沿能量降低的方向靠近，最后得到一个优化的边界。-Snake algorithm or Active Contour Models. Such algorithms need to give the initial profile, and then proceed to iteration, so that contours along the direction of lower energy around, and finally get an optimization of the border.

To run it with GUI 1. Type guide on the matlab prompt. 2. Click on "Go to Existing GUI" 3. Select the snk.fig file in the same directory as this file 4. Click the green arrow at the top to launch the GUI Once the GUI has been launched, you can use snakes by 1. Click on "New Image" and load an input image. Samples image are provided. 2. Set the smoothing parameter "sigma" or leave it at its default value and click "Filter". This will smooth the image. 3. As soon as you click "Filter", cross hairs would appear and using them and left click of you mouse you can pick initial contour location on the image. A red circle would appear everywhere you click and in most cases you should click all the way around the object you want to segment. The last point must be picked using a right-click in order to stop matlab for asking for more points. 4. Set the various snake paramete

[Technology Management] Active-Contour-Models- DL : 0: 　传统Snake 模型存在的缺点是, 其初始轮廓必须靠近图像中感兴趣目标的真实边缘,否则会得到错误结果,且由于Snake 模型的非凸性,结果不能进入感兴趣目标的深凹部分,很容易陷入局部极小点. 由此该文提出一种基于力场分析的主动轮廓模型,详细分析了基于欧氏距离变换的距离势能力场分布,归纳出感兴趣目标上真轮廓点与假轮廓点的判别标准. 建立了由曲线能量到最终结果的有效方法,避免了Snake 陷入局部极小点. 实验结果表明,该模型具有较大的捕获区域,能够进入感兴趣目标的深凹部分,准确提取感兴趣目标的轮廓. 与GVFSnake 模型相比, 该模型具有很小的计算量.-The t raditional snake initial contour should be close to the t rue boundary of interested ob2 ject in an image , or else it would converge to the wrong result . Next , active contours have difficulties progressing into boundary concavities. Moreover , the t raditional snake and it s almost kinds of im2 proved methods are easy to get into local minimum because snake models are non2convex. An active contour model based on force field analysis , namely FFASnake model , is presented in this paper. Based on analyzing force dist ribution rules of distance potential force field , a standard is int roduced here to distinguish the false one f rom contour point s.
