盲水印嵌入提取-已实现

基于巴谷星表星挑选出等小于2的恒星，利用matlab实现可生成任意方向的导航星星图以作为天文导航识别定位定姿依据的程序。(Pick out the star catalog prakob etc. less than 2 stars for navigation based on star map can be generated in any direction as celestial navigation positioning and orientation according to the recognition procedure using matlab.)

正方体透视投影变换,可通过鼠标及键盘实现动画效果(cube perspective projection transform, through mouse and keyboard to achieve animation effects)

用matlab实现了一系列示例：球差，慧差，像差，像散。(Using matlab to achieve a series of examples: spherical aberration, coma, aberration, astigmatism.)

说明：  一个很有用的Markov Decision Process matlab程序(a very useful Markov Decision Process procedures Matlab)

降低正交频分复用ofdm系统的峰值平均功率比的仿真(Reduce the Orthogonal Frequency Division Multiplexing OFDM system peak-average power ratio simulation)

说明：  用于计算图像的空间频率和空间频率图（可看作是图像的轮廓）(Used to calculate the spatial frequency and spatial frequency graph of the image)

人工神经网络实现人脸识别，matlab代码(Artificial Neural Network for Face Recognition)

说明：  颗粒粗化源码，将马赛克现象认为的作用于一副图像，称之为颗粒粗化。可以用来建立图像切换效果(source of coarse particles, that the phenomenon will mosaics in the role of an image, known as particle coarsening. Images can be used for switching effects)

说明：  基于人类视觉系统HVS的小波域数字图像水印 包含：嵌入、提取、分解、重构等(Based on human visual system HVS digital image watermarking in wavelet domain include: embedding, extraction, decomposition, reconstruction, etc.)
