Because of the traditional snake has not converge to the concave regional and shortcomings such as slow convergence, by improving the external energy, the introduction of the gradient vector flow active contour model (GVF Snake). Experiments show that the method can be faster and better convergence in the image contour.

Description: 图像分割是由图像处理到图像分析的关键步骤，涉及到计算机视觉技术的复杂问题。在医学图像方面，许多应用大都依赖于对图像中目标轮廓的准确提取。基于微分算子检测的方法几乎都对噪声较为敏感且不能保证得到连续的边缘，无法用于辨识和分析目标。由Kass提出的基于主动轮廓线的Snake模型[1]，用一个具有一定弹性的封闭曲线，在曲线自身形状约束力和由图像数据计算而来的外部力的共同作用下演化，来逼近目标边界，完成对图像的分割。
GVF snake VC++做的-Image segmentation by image processing to image analysis of the key steps involved in computer vision technology to complex problems. In medical images, many applications largely depends on the target images extracted contour accuracy. Based on the differential operator method of detecting almost all more sensitive to noise and can not guarantee that they will get straight edge, can not be used for target identification and analysis. Kass raised by the active contour based on the Snake model [1], with a certain flexibility of the closed curve in the curve shape their own binding and calculated by the image data from the external force under the joint effect of the evolution of the boundary to approximate the target , completion of the image segmentation.

Description: gvf snake 邊緣檢測範例(包含範例圖)-1. Introduction and Installation Instructions
----------------------------------------------
Welcome to the Gradient Vector Flow (GVF) Active Contour Toolbox. The
Matlab*.m files in this software distribution implement our GVF snake,
the original (Kass, Witkin, and Terzopoulos) snake, the balloon snake,
and the distance snake. These programs were designed, written and tested
by Chenyang Xu and Jerry Prince.
To install this software, simply unzip the file into an empty directory,
making sure to ask your unzipper program to restore the directory
structure of the zipped files. In this documentation, we will assume
that you have unzipped the files into C:\GVF.
2. Documentation
----------------
We have included two research papers that describe GVF. You can find
these in C:\GVF\papers.
Brief descriptions of the software modules can be found in this file
below. For more detail, you should run Matlab, add the path
C:\GVF\snake, and type "help function-name". F

实轮廓。实验结果表明，此方法有效地缩小了搜索的范围，减少了GVF迭代次数，提高了轮廓收敛的
速度，并保留了GVF Snake模型的所有优点。-: The gradient vector flow (GVF) field iterative convergence process and outline the time cost, could not approach the more complex contours of such deficiencies, a new method of setting the initial contour. Wavelet-based multi-scale contour detection algorithm can accurately locate the various types of contours, on the basis set to a very good initial contour close to the image in a variety of real contours. Experimental results show that this method effectively reduces the search and reduce the number of iterations of the GVF to improve the convergence speed profile, and retained all the advantages of GVF Snake model.
