小波去噪的程序，很好用，推荐给大家使用。(Wavelet denoising procedures, very easy to use, recommended for everyone to use)

说明：  用小波变换对图像进行三级分解及求出各个子带系数(Using wavelet transform image decomposition and find three different sub-band coefficients)

实现对一幅灰度和彩色图像作的离散余弦变换,选择适当的DCT系数阈值对其进行DCT反变换.(The realization of a piece of gray and color images for the discrete cosine transform, select the appropriate thresholds for DCT coefficients of its inverse transform DCT.)

线性反投影算法（Linear Back Projection，简称 LBP）又称累加法，是最早使用的一种简单（ECT图像重建）成像算法。它将通过某点的所有投影射线进行累加，再反向估算出该点的密度值。从成像观点分析，它是不完全的雷登逆变换（完整的雷登逆变换包括微分、希尔伯特变换、反投影和归一化等步骤）。(Linear back projection algorithm (Linear Back Projection, referred LBP), also known as cumulative method, is the first to use a simple (ECT image reconstruction) imaging algorithms. It accumulates all projection rays through a point, then reverse the estimated density value of the point. From the image point of view analysis, it is not exactly the inverse transform Leiden (Leyden complete inverse transformation involving differential Hilbert transform backprojection and normalization steps, etc.).)

主要功能是实现相机标定，以及实现反投误差，实现特征点的提前。(The main function is to achieve camera calibration and error to achieve the anti-investment, to achieve the feature points in advance.)

说明：  这是一篇关于大气湍流退化图像复原的硕士论文，我用matlab对该论文中阐述的方法进行了仿真(This is a master's thesis on the restoration of atmospheric turbulence degraded images. I used Matlab to simulate the methods described in this paper.)

说明：  再来一个绘图程序，花了我一个上午时间才搞定。(then a drawing program, I spent a morning time to get.)

Richardson-lucy去噪算法，泊松去噪(image denoising use Richardson lucy algorithm)

BMP和JPEG数据格式的图片读取与写入操作，有完整的代码(BMP and JPEG data format images read and write operations, complete code)

基于彩色图像的加密方法，其中采用的是图像置乱加密的算法(Based on color image encryption method, which USES the image scrambling encryption algorithm)
