用matlab图像处理工具箱进行canny边缘检测(Matlab image processing toolbox with canny edge detection)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

滑模控制，包括控制对象（机械臂），控制系统以及轨迹调整(sliding-mode control,including control plant,control system and trajectory deformation)

对语音信号假入宽带高斯白噪声并用小波降噪(add white noise to signal and decrease it with wavelet)

用matlab实现的神经网络识别字母的程序，识别率达到100 。(Program of neural network regnizing letters using MATLAB, the accuracy is up to 100 )

说明：  BCH 编解码的MATLAB 实现。BCH码是一类重要而有效的纠正多个随机错误的循环码，由于该码具有严格的代数结构，所以是到目前为止研究得最为详尽、应用最为广泛的一类码，已有多种译码算法。(BCH codec of MATLAB. BCH is a kind of important and effective redress the wrong number of random cyclic code, as the code strictly algebraic structure, it is so far the most detailed study in, the most widely used type of a code has a variety of decoding algorithm.)
