To detect skin color based on threshold. Using simple method , with LOC less than 100 but efficient

利用卡尔曼滤波、滑模观测器和锁相环实现无传感器控制，曲线效果比较合理(Sensorless control is realized by Kalman filter, sliding mode observer and phase-locked loop. The curve effect is reasonable.)

上传了关于解模糊的基本程序，如中国余数定理，余差法等等(From vague on the solutions of the basic procedures, such as the Chinese remainder theorem, and so on more than bad law)

图像处理之人脸识别，基于数学形态学的边界提取(Image processing of face recognition, based on mathematical morphology for edge extraction)

K-nearest neighbors 搜索 聚类时经常使用的一种方法 国外网站转载( The following utilities are provided: - Nearest neighbor - K-Nearest neighbors - Radius Search They al supports N-dimensions and work on double, it is possible to choose if return the distances.

这是篇关于matlab环境下的数字滤波器的论文，基于Matlab的FIR滤波器设计及FPGA实现(This is a chapter on the environment matlab digital filter paper, based on Matlab for FIR filter design and FPGA implementation)

自己写的matlab上GUI界面，可以读取行情软件导出的txt格式历史数据，并汇出k线和技术指标，可以通过GUI编辑设置、各种指标及其参数。主图附图指标编辑通过编写脚步实现，有例子。 解压后，将work下的dir.mat中的wkdir变量修改成与你放置的目录一致，也可以就将work放置在"d:/matlab/"下. read2mat.m从文本中读取数据，并存在与文本文件同名的.mat格式的文件中。 运行kfigure,加载.mat格式文件就可以画出k线图和指标图。其他功能很多和股票软件差不多，大家自己试就行了。(Matlab GUI interface to write their own, you can read the historical data of market software exported txt format, and Export k lines and technical indicators, you can edit the settings through the GUI, various indicators and their parameters. The the main figure drawings indicators edit achieve by writing the footsteps examples. After decompression, modify the work under dir.mat wkdir variable and you are placed in the same directory, will work placed in the " d :/ matlab /" . Read2mat.m to read data from a text, and exist with a text file of the same name. mat format file. The run kfigure, loading mat format file can draw k chart and indicators Figure. Other features and stock software almost everyone own try line.)

基于matlab的GUI开发的一款简单的用于学生成绩查询的数据管理系统框架。(Based on matlab GUI development. )
