中文说明：包括调制，解调，信噪比计算，使用大量的有限元法求解偏微分方程，在matlab环境中自动识别连通区域的大小,能量熵的计算，多姿态，多角度，有不同光照,添加噪声处理。
English Description：
Including modulation, demodulation, signal to noise ratio is calculated, using a large number of finite element method for solving partial differential equations, in the MATLAB environment, automatic recognition of connected region size, energy entropy calculation, a multi pose, multi angle, different illumination, add noise to deal with.
