上传一张图片，这是在做图像水印研究时常用的一张lina图(image used in watermarking)

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.).)

自己总结的JPG、GIF、BMP、PNG、WBMP图片文件格式文档以及相关参考标准与SPEC(their lessons JPG, GIF, BMP, PNG, WBMP picture files and related documentation and reference standard SPEC)

Image analysis to create a histogram in python language

说明：  这是个读取视频中每一帧并按顺序保存的小工具，因网上现成的太少，故自己编写(This is a small tool for reading vedio and save every frame in it .)

图像识别算法，使用点阵方式识别图片，借用Tessnet2.zip 组件，用来进行图片文字/图片数字识别(Tessnet2.zip use to be Image recognise)

单像素相机是基于压缩传感理论实现的，是数码相机发展的另一个革命性的方向，包括了所有单像素前沿的文献(Single-pixel camera is based on compressed sensing theory to achieve, is another revolutionary development direction of digital cameras, including the literature of all single-pixel frontier)

JSteg隐写技术matlab实现代码--基本思想：用秘密信息比特直接替换JPEG图像中量化后DCT系数的最低比特位，但若量化后DCT系数为0或者1，则不进行处理。（DCT系数的LSB嵌入） (JSteg steganography matlab code- the basic idea: direct replacement with the secret information bits JPEG image quantized DCT coefficients in the least significant bit, but if the quantized DCT coefficient is 0 or 1, no processing. (DCT coefficients LSB embedding))

求取信号的峰值点。可以通过设置信号峰值范围、信号幅度来确定特定的峰值点。(The peak point of the signal to strike. Can set the scope of the signal peak, the signal range to determine the specific point of the peak.)

我用VC编的一个画图程序：其中使用了切分视图(I VC series a drawing program : the use of split View)
