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:GVFpapers. Brief descriptions of the software modules can be found in this file below. For more detail, you should run Matlab, add the path C:GVFsnake, and type "help function-name". F)

说明：  多径信道信噪比（Signal-to-noise ratio），简称SNR，这三个字经常会出现在各种文章、文献、产品说明书中，然而它并不是简单的一个通信专业名词，而是一个无处不在的衡量天枰。它可以衡量一个人的生活状态、工作状态，可以衡量爱人间、朋友间的情感交流效率，同样也可以衡量一个社区或是一个系统的运行状态。(multiple Path Channel)
