中文说明： 基于matlab平台实现,包括面积、周长、矩形度、伸长度，包括 MUSIC算法，ESPRIT算法 ROOT-MUSIC算法，通过反复训练模板能有较高的识别率，随机调制信号下的模拟ppm，解耦，恢复原信号。
English Description：
Based on the MATLAB platform, including area, perimeter, rectangularity, stretching the length of the, including the music algorithm, ESPRIT algorithm Root-MUSIC algorithm, through repeated training pattern can have higher recognition rate, random modulation signal simulation ppm, decoupling, recovery of the original signal.
