image prcessing: histogram, negative, thresholding

说明：  基于小波神经网络的预测算法，MATLAB下通过，效率较高。(Wavelet neural network based prediction algorithm, MATLAB adopted under, more efficient.)

EMD 方法在理论上可以应用于任何类型的信号的分解， 因而在处理非平稳及非线性数据上，具有非常明显的优势,适合于分析非线性、非平稳信号序列，具有很高的信噪比。(EMD decomposition method in theory can be applied to any type of signal, which in the non-stationary and nonlinear data, with a very distinct advantage, suitable for analyzing nonlinear and non-stationary signal sequence, with a high signal to noise ratio .)
