EulerMethod-DifferentialEquations

用matlab实现视频帧的目标提取,能达到较好的提取效果，具体方法为帧差法(Using matlab to achieve the goal of video frame extraction, the extraction can achieve better results, specific methods for the frame difference method)

In his 1960 famous publication (“A new approach to linear filtering and prediction problems”, Trans.ASME J. Basic Engineering., vol 82, March 1960, pp 34-45), Rudolf Kalman based the construction of the state estimation filter on probability theory, and more specifically, on the properties of conditional Gaussian random variables. The criterion he proposed to minimize is the state vector covariance norm, yielding to the classical recursion : the new state estimate is deduced from the previous estimation by addition of a correction term proportional to the prediction error (or the innovation of the measured signal).

this compress program can be extracted to a text file that can be copied to mse.m. a matlab program that calculate the mean square eeror for video in the format of yuv such as the test sequence
