实现三层神经网络,对于初学者帮助较大。但是讲解不是很全面，几乎没有。-The realization of three neural networks, for beginners to help more. But on the not very comprehensive, virtually non-existent.

BP神经网络用于函数拟合与模式识别，非常适合计算机视觉方面的研究使用,实现了图像的加水印，去噪，加噪声等功能。- BP neural network function fitting and pattern recognition, Very suitable for the study using computer vision, Realize image watermarking, de-noising, plus noise and other functions.
