adaptive median filter

NN算法实现数字卡片的识别，输出0-9的奇偶识别，Matlab下实现(NN algorithm identification card number, the output parity 0-9 recognition, Matlab to achieve)

说明：  利用MATLAB进行飞行器四自由度仿真。(Four degrees of freedom for vehicle using MATLAB simulation.)

当物体表现出最讯息时有最大的乱度。 当Entropy最大，影像有最大的讯息。(objects displayed at the most messages have the greatest degree of chaos. When the maximum entropy, images have the greatest message.)

MATLAB中提供了汉明码的编解码、4FSK调制解调函数和不同通信信道模型函数，本程序直接调用进行编程。借助于MATLAB可大大地拓宽研究分析的视野提高研究设计的效率,具有重要的推广和应用价值。 (MATLAB provides the hamming codec 4FSK modem function and different communication channel model function, the program calls directly programming. Help of MATLAB can greatly broaden the horizons of research and analysis to improve the efficiency of the study design, with promotion and application value.)

说明：  给出轨道根数，求初始位置与速度并作图。其中地球以真实比例缩放画出(Gives the orbital elements, find the initial position and velocity, and mapping. Which to draw the earth to the true scaling)
