在matlab中实现标准条形码识别，设计带背景条形码图片分割与定位(To achieve standards in matlab bar code recognition, bar code design with the background picture segmentation and positioning)

说明：  适用Otsu方法做阈值分析。阈值决策的依据是最大类间方差，这种方法的依据就是类间方差，本程序仅仅适用与二分类问题。(thresholding algorithm using Otsu)

this is the source for manhattan mobility model in matlab it gives the path of movement

进行FFT变换，可以进行2纬fft，最原生的FFT程序。(FFT transform)

基于matlab的峰值检测算法,具有较为直观地意义，系数可以根据实际需要进行调节(Matlab-based peak detection algorithm, with a more intuitive sense, the coefficients can be adjusted according to actual needs)

lpc语音信号合成，给出了完整的LPC matlab程序，包括语音信号采集，LP预测系数(failed to translate)
