附件的代码为Gabor变换的源代码，运行正常，并且非常实用。(Annex Gabor transform code for the source code, operating normally, and very practical.)

仿射不变特征提取 多尺度自卷积方法。。。。。。。。。。。。。。。。。。。(The Multi-Scale Autoconvolution (MSA) method offers a novel way of approaching this problem. The method provides affine invariant features with only moderate computational complexity and does not require any other segmentation steps than background elimination.)

张正友相机标定程序 张正友摄像机标定法是一种简单实用的标定法，本次试验中共取用了同一摄像机从不同角度拍摄的六幅图像，经过Harris角点提取并优化从每幅图像中取十个特征点来进行摄像机标定（这十个点的世界坐标相同）。(Zhang Zhengyou camera calibration procedure Zhang Zhengyou camera calibration method is a simple and practical calibration method, this test CCP access to the six images of the same camera taken different angles, through Harris corner extraction and optimization take ten each image camera calibration feature points (the same world coordinate these ten points).)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)
