matlab code for Local binary patterns

说明：  利用matlab进行sift特征匹配，有需要的可以下载利用相关函数(Using MATLAB to match SIFT features, we can download and use correlation functions)

说明：  在神经网络中用求协方差矩阵的方法对人脸图像进行压缩及恢复(In the neural network covariance matrix using the method of face image compression and restoration)

设计了一种具有异周期毗邻结构的新型循环前缀,提出了相应的OFDM 频偏估计算法。该异周期毗邻结 构循环前缀由CP1 和CP2 两部分构成,使OFDM 符号具有双周期特征。通过引入较短的CP1 ,牺牲极少的资源, 可以有效克服现有频偏估计方法中的固定频偏估计范围的缺陷,同时具有频偏估计范围大,精度高的特点。(This paper proposes a heter2cycle abutted CP st ructure and a two2step OFDM carrier f requency calibration algorithm. The cyclic prefix of the new cyclic prefix is made up of CP1 and CP2 , which provide the character of double2cycle for OFDM symbol. By int roducing a short CP1 , the proposed algorithm can overcome the defect of fixed f requency off set estimation range in current f requency estimation method , and achieves larger f requency esti2 mation range while obtaining fine f requency calibration.)

iris标准数据集 模式识别； matlab环境(iris data)

说明：  利用C#创建窗体，通过设置按钮，同时利用按钮实现各种功能。此代码实现的功能是1、调用函数；2、显示照片，同时还能消除照片；3、通过调用MATLAB，实现图像显示的函数。(Use C# to create a form, by setting the button using the button at the same time to achieve various functions. This code implements the function is 1, call the function 2, display photos, while eliminating photographs 3, by calling MATLAB, the function of image display.)
