说明：  采用自适应非局部降噪的算法对图像进行去噪处理，能够实现不同算法的降噪处理(Using adaptive non-local denoising algorithm to denoise image can achieve denoising processing of different algorithms.)

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.).)

自己实现的BM3D图像去噪算法。它首先把图像分成一定大小的块，根据图像块之间的相似性，把具有相似结构的二维图像块组合在一起形成三维数组，然后用联合滤波的方法对这些三维数组进行处理，最后，通过逆变换，把处理后的结果返回到原图像中，从而得到去噪后的图像。(Image Denosing by Sparse 3-D Transform-Domain Collaborative Filtering.)

关于大视场的视觉标定方法，相对于目前很多近距离的标定，很有借鉴作用(tisi is a paper about fast calibration for binocular vision measuring system,and it s with a large field)

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

gif格式图片生成，包括动画生成，是非常好的入门学习资料。(gif format image generation, including animation generation, is a very good learning materials.)

一种基于matlab编写的免疫遗传算法程序,比较好,不过我看不懂(An immune genetic algorithm based on matlab procedures, is better, but I don t understand)

convert bmp to rgb565(algorithm to handle all kinds of bmp to rgb565)

基本图像处理用C++的实现。包括平移旋转翻转边缘提取canny算子等(The basic image processing with C + +.)

快速ＤＣＴ变换的代码.利用c++实现DCT变换.(Fast DCT transform code. Use c++ to achieve DCT transform.)
