说明：  提取图像的颜色特征，首先将图像颜色映射到指定的8个颜色，然后利用自相关和互相关计算得到图像的特征向量，并从原数据库中算出利用此方法检索图像的正确率，并将检索结果好的图像显示到指定文件夹中。(Extract image s color characteristics.First, the image color map to the specified eight colors, then use the auto-correlation and cross-correlation calculation of image feature vectors.and Calculated from the original database, retrieve the images using this method, the correct rate, and a good image display search results to a specified folder.)

发送装置：随机信号产生、脉冲成型（上采样可调，滚降可调）； 发送：AWGN信道（信噪比范围可调） 接收设备：QPSK调制解调 ，匹配滤波，判决 画出接收信号的眼图、星座图；计算误码率并与理论值比较。 (Transmitting device: random signal generator, pulse shaping (the sampling adjustable, adjustable roll-off) Send: AWGN channel (SNR range is adjustable) Receiving equipment: QPSK modulation and demodulation, matched filtering, judgment   BER is calculated and compared with the theoretical value draw the received signal eye diagram, constellation.)

张正友的标定工具箱，直接运行会有错误，这是经过修改的工具箱，首先运行calib_gui,确认图像目录在current directory里，然后运行calib_gui_normal,出现图形界面，读取图像，进行标定(Zhang Zhengyou calibration kit, run directly there will be a mistake, this is the modified toolbox, first run calib_gui, confirm the image directory in the current directory, then run the calib_gui_normal, graphical interface, read the image, to carry on the calibration)
