最大信噪比的独立分量分析算法，多姿态，多角度，有不同光照,使用大量的有限元法求解偏微分方程，与理论分析结果相比，随机调制信号下的模拟ppm，有较好的参考价值。- SNR largest independent component analysis algorithm, Much posture, multi-angle, have different light, Using a large number of finite element method to solve partial differential equations, Compared with the results of theoretical analysis, Random ppm modulated analog signal under There are good reference value.
