用matlab实现的神经网络程序，识别样本图像A-Z，并用相应的数字0-26显示，验证识别能力和容错性。-Achieved using matlab neural network program, the the identification sample images AZ, and displayed with the corresponding figures 0-26, verify identification and fault tolerance.

实现图像识别，基于小波变换实现图像特征提取，然后神经网络进行训练(The image recognition is realized, the image feature extraction is realized based on wavelet transform, and then the neural network is trained.)
