用神经网络，实现手写数字0-9的识别，对于相似度小的拒绝识别(Using neural networks, implementation figure 0-9 handwriting recognition, the similarity of small refuse recognition)

说明：  数据 采集 应用Matlab软件通过控制声卡进行数据采集

对于遥感影像亚像元尺度信息的获取，常用手段就是混合象元分解(spectral unmixing)

计算赫斯特指数Calculates the generalized Hurst exponent H(q) of a stochastic variable x(t) (a time series) the scaling of the renormalized q-moments of the distribution <|x(t+r)-x(t)|^q>/<x(t)^q> ~ r^[qH(q)] The value of H(q) give indication about the fractal nature of the signal. H(q) = 0.5 corresponds to a Brownian motion, deviations form 0.5 and dependency on q are indications of multi-fractality and time-correlations.(Calculates the generalized Hurst exponent H(q) of a stochastic variable x(t) (a time series) the scaling of the renormalized q-moments of the distribution <|x(t+r)-x(t)|^q>/<x(t)^q> ~ r^[qH(q)] The value of H(q) give indication about the fractal nature of the signal.
