MatLabV1.0最初的matlab版本，大家可以试着玩玩！(MatLabV1.0 initial version of Matlab, we can try to play!)

The aim of this paper is to describe a novel and completely automated technique for carotid artery (CA) recognition, far (distal) wall segmentation, and intima–media thickness (IMT) measurement, which is a strong clinical tool for risk assessment for cardiovascular diseases. The architecture of completely automated multiresolution edge snapper (CAMES) consists of the following two stages: 1) automated CA recognition based on a combination of scale–space and statistical classification in a multiresolution framework and 2) automated segmentation of lumen–intima

This code demomstrates an improved algorithm based on the local binary fitting (LBF) model in Chunming Li et al s paper: "Minimization of Region-Scalable Fitting Energy for Image Segmentation", IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008. Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows. Run the Demos in the M-files for several test images. Once an image comes out, click the mouse to generate a polygon as the initial contour: left click to get a number of points, then right click to get the end point. The number of iterations may need to be increased if the initial contour is too far away from the desired object boundary.

仿真8-PSK载波调制信号在AWGN信道下的误码率和误比特率性能，并与理论值相比较。(Under the simulation 8-PSK carrier modulation signal s and harms the bit rate performance in AWGN channel error rate, and compares with the theoretical value.)

此程序为一维层状各向同性介质正演程序，输入各层电阻率及厚度，结果得到视电阻率和相位(It is a MT forward procedure about layered isotropic medium, input the resistivity and thickness of each layer, you ll get the apparent resistivity and phase)

基于matlab平台的蚁群聚类算法 很有用 (ant clusting)

garch族（garch,garchs,garchsk,gjr）模型的参数模拟，以及风险值 VaR 在不同水平下的估算。(garch group (garch, garchs, garchsk, gjr) parameters of the simulation model, and the estimated risk value VaR at different levels.)

说明：  对原有修正PRI变换进行改进，将分散在真实PRI箱附近几个箱中的到达时间差值累加起来，提高检测性能(PRI transform the original amendment to improve, will be scattered around a few boxes in the real PRI box add up to the arrival time difference and improve the detection performance)

FIR低通滤波器设计，运行通过，通过改变滤波器参数，可以得到不同阶数的滤波器，加有随机噪声的语音信号通过滤波器后会有很大改善。(FIR low-pass filter design, to run through, can be obtained by varying the filter parameters, the number of filters of different orders, and added with the random noise of the speech signal through the filter will be greatly improved.)
