应用matlab把avi视频分割成若干图像序列(segment avi video into a number of image sequences by using matlab)

利用STFT可以估计信号在每片短时窗内的频率得到信号的瞬时频率，该曲线由一组时间和频率相对应的点组成，反映了信号频率随时间的变化。(Using STFT can estimate the frequency of the signal in every piece of short-time window get signal instantaneous frequency, the curve consists of a set of time and frequency of corresponding points, reflects the signal frequency changes over time. )

自己在生活中的比较有用的matlab程序，希望对大家有用。。。(Their useful life of the matlab program, useful for all of us hope. . .)

BP（Back Propagation）网络是一种按误差逆传播算法训练的多层前馈网络，是目前应用最广泛的神经网络模型之一。 BP网络能学习和存贮大量的输入-输出模式映射关系，而无需事前揭示描述这种映射关系的数学方程。 它的学习规则是使用最速下降法，通过反向传播来不断调整网络的权值和阈值，使网络的误差平方和最小。BP神经网络模型拓扑结构包括输入层（input）、隐层(hide layer)和输出层(output layer)。 通过对信息的提取以及记忆，用作分类、聚类、预测等。 (BP (Back Propagation) network is a pre-press error back propagation algorithm Multilayer feedforward network, is one of the most widely used neural network model. BP network can learn and store a large amount of input- output mode mapping without prior reveal mathematical equations that describe the mapping relationship. It s learning rule is to use the steepest descent method, by reverse spread to constantly adjust the network weights and thresholds and the minimum sum of squared error of the network. BP neural network topology comprises an input layer (input), hidden layer (hide layer) and an output layer (output layer). By extracting information and memory, it is used as classification, clustering, prediction.)
