Description: snakes are a variational technique to find the best contour that aligns with an image. The basic routine, snake.m, aligns a sequence of points along a contour to the maximum of an array or image. Provide it with an image, a set of starting points, limits on the search space and it returns a new set of points that better align with the image.

Description: 用三角网法绘制等值线，是在三角形的三条边上用线性内插方法寻找等值点，这种方法的机理是将每个三角形看作是空间的一个平面，这就要求在每个三角形的三个顶点内的地貌形态无明显的变化，故此希望将其中最靠近的三个点构成三角形，以符合上述机理，使插补的等值点精度较高，更好的反映地貌的实际形态。符合这些条件的三角形称之为“最佳三角形”-With a triangular mesh contour map is the edge of the triangle with the three methods of linear interpolation to find the equivalent point, the mechanism of this method is to each triangle as a space plane, which requires each triangles three vertices with no obvious patterns of geomorphic change, it wished to put the three points closest to constitute a triangle in order to comply with the above mechanism, so that the equivalent interpolation points higher accuracy, better reflects the landscape the actual shape. Applying these criteria to the triangle known as the

Description: 一种比较好用的边缘检测方法CORNER Find corners in tensity image.
％ CORNER works by the following step:
％ 1. Apply the Canny edge detector to the gray level image and obtain a
％ binary edge-map.
％ 2. Extract the edge contours from the edge-map, fill the gaps in the
％ contours.
％ 3. Compute curvature at a low scale for each contour to retain all
％ true corners.
％ 4. All of the curvature local maxima are considered as corner
％ candidates, then rounded corners and false corners due to boundary
％ noise and details were eliminated.
％ 5. End points of line mode curve were added as corner, if they are not
％ close to the above detected corners.-A more useful edge detection method CORNER Find corners in tensity image. CORNER works by the following step: 1.

Description: 在识别图像中的目标时，往往需要对目标边缘作跟踪处理，也叫轮廓跟踪。顾名思义，轮廓跟踪就是通过顺序找出边缘点来跟踪边界的。-Images in the identification of targets, the target is often necessary for tracking the edge of treatment, also called contour tracking. As the name suggests, contour tracing is to find the edge point of order to track the border.

Description: This paper provides an algorithm for partitioning grayscale images into disjoint regions of coherent
brightness and texture. Natural images contain both textured and untextured regions, so the cues of contour and
texture differences are exploited simultaneously. Contours are treated in the intervening contour framework, while
texture is analyzed using textons. Each of these cues has a domain of applicability, so to facilitate cue combination we
introduce a gating operator based on the texturedness of the neighborhood at a pixel. Having obtained a local measure
of how likely two nearby pixels are to belong to the same region, we use the spectral graph theoretic framework of
normalized cuts to find partitions of the image into regions of coherent texture and brightness. Experimental results
on a wide range of images are shown.

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
