航天器的飞行动力学计算，航空航天参数分析(Spacecraft flight dynamics calculations，Aerospace parametric analysis )

一种基于小波变换的灰度数字水印嵌入算法,使用matlab实现，含有原始论文。不过不是很理想，希望大家改进(Gray-scale based on wavelet transform digital watermark embedding algorithm, using matlab implementation, containing the original papers. But not very good, hope that we improve the)

matlab编制的通过卷积完成特征点匹配的软件(match image feature points by correlation)

基于运动生成模糊图像，并用维娜滤波器去除模糊(Generated based on motion blurred images, and remove the fuzzy filter with Vina)

说明：  图像压缩去噪增强锐化程序，供大家参考。 包括：数字图像矩阵数据的显示及其傅立叶变换 二维离散余弦变换的图像压缩 采用灰度变换的方法增强图像的对比度 采用二维中值滤波函数medfilt2对受椒盐噪声干扰的图像滤波 采用MATLAB中的函数filter2对受噪声干扰的图像进行均值滤波 图像的自适应魏纳滤波 运用5种不同的梯度增强法进行图像锐化 图像的高通滤波和掩模处理 利用巴特沃斯（Butterworth）低通滤波器对受噪声干扰的图像进行平滑处理 利用巴特沃斯（Butterworth）高通滤波器对图像进行锐化处理-(Sharpen Image Compression Denoising enhanced procedures for your reference. Include: digital image data display matrix and its Fourier transform two-dimensional discrete cosine transform image compression method using gray-scale transformation of the contrast-enhanced images using two-dimensional median filter function by medfilt2 of salt and pepper noise image filtering using MATLAB The function affected by noise interference filter2 images mean filter Adaptive Image Filtering Wehner use five kinds of different gradient method to enhance image sharpening images of high-pass filtering and mask treatment using Butterworth (Butterworth) low pass filter noise by smoothing the images deal with the use of Butterworth (Butterworth) high-pass filter for sharpening images treatment)

采用matlab编写，对图像椒盐噪声与周期性噪声的进行滤除(Using matlab, image noise and periodic noise salt and pepper to filter out)

说明：  该算法适用于各种非线性，非平稳的信号，对于数据的分析较透彻。(The algorithm is suitable for various non-linear and non-stationary signals, and the data analysis is more thorough.)

Kalman filter. Implemented in MATLAB.
