ORTHOFIT Fit polynomial to data. YS = ORTHOFIT[X,Y,N] smooths/fits data Y[X] in a least-squares sense using a polynomial of degree N and returns the smoothed data YS.

Object tracking in computer vision refers to the task of tracking individual moving objects accurately from one frame to another in an image sequence. Several tracking methods have been proposed in the recent literature capable of coping with a certain degree of occlusions of the objects.

浙江大学的关于提取图像背景的报告（matlab），里面的方法给我很多启示，希望也能给你们一些启示，由于本人是初学者，有些方法还是看不懂！(Zhejiang University, on the extraction of image background report (matlab), inside the method for giving me a lot of inspiration, hope and also give you some inspiration, because I am a beginner, and some way to watch or do not understand!)

IMAQPLOT is a simple demonstration of previewing video data using the toolbox s TimerFcn callback. IMAQPLOT also allows users to integrate the video preview into any MATLAB GUI. These are capabilities that are present in the toolbox s PREVIEW command, but are presented here as a demonstration of TimerFcn callback. Using toolbox callback properties, you can configure a video input object to generate a live image plot display. Do you want a basic preview window created for you? Simply call: obj = videoinput( matrox , 1) obj.TimerFcn = @imaqplot obj.TimerPeriod = 0.1 obj.FramesPerTrigger = Inf start(obj) Do you want to add a preview window to an existing GUI? Simply provide IMAQPLOT a handle to an image object and it will update it for you: obj = videoinput( dt , 1) obj.TimerFcn = {@imaqplot, hImage} obj.TimerPeriod = 0.1 obj.FramesPerTrigger = Inf start(obj)

说明：  基于dct的数字水印技术，能够应用于版权技术等方面，希望能与大家分享。(Dct-based digital watermarking technology can be applied to other aspects of copyright technology, hoping to share with you.)

说明：  利用FDTD方法模拟普通光子晶体光纤中模场变化的情况，为主程序，可以为学习FDTD模拟PCF的学习者提供一定参考和学习。(Ordinary FDTD simulation using photonic crystal fiber mode field changes in the situation, the main program, you can learn from FDTD simulation for the PCF to provide a reference of learners and learning.)

平面波展开法计算的二维声子晶体带隙，分别是正方与圆形散射体形成正方格子声子晶体，最后输出了能带图的数据，需要自己用画图软件画出来。(Plane wave expansion method to calculate the band gap of two- dimensional phononic crystals, which are square with rounded square lattice formed scattering crystal, the final output of the energy band diagram of the data, so you need to use drawing software drawn.)
