一种基于DCT变换的数字水印算法的实现过程,水印为伪随机序列，包括嵌入和提取两个过程。其中textmark.m为攻击实验代码。(DCT-based Digital Watermarking Algorithm Transform realize the process, the watermark for the pseudo-random sequence, including both the process of embedding and extraction. Textmark.m experiment in which the attack code.)

在matlab环境下对两幅图像进行配准，输出配准参数，显示配准结果(In the matlab environment for registration of two images, output registration parameters, shows the registration results)

压缩感知的快速Laplace恢复算法,算法适用于超完备字典(the Beyes recovery algorithms are similar to the sparse coding based on the over-complete dictionary. )

matlab加载一个视屏，转化成每帧图片加以保存。(Matlab loads a video screen and translates it into pictures for each frame to be saved.)

此程序为指纹识别中重要一步指纹分类的MATLAB源码(This program is an important step in fingerprint identification fingerprint classification MATLAB source code)

对两帧图像进行ICM调试.包含内容：1估计姿态和摄像机内参数；2两幅图做四次金字塔；3利用输入特征点采用ransac算法估计姿态R, T。4sift特征匹配；5摄像机标定。(ICM images on two debugging. Contains: 1 Estimated posture and intrinsic parameters 2 two plans to do four pyramids 3 using the input feature points using ransac algorithm estimates gesture R, T. 4sift feature matching 5 camera calibration.)

说明：  利用已知的平坦道路的视差图，得出uv方向的直方图，并且求出直线(The histogram of the UV direction and the straight line are obtained by using the disparity map of the known flat road.)

使用二维经验模态分解进行图像的去噪操作，内含三幅测试图片和说明文档(Using Bi-dimensional Empirical Mode Decomposition for image denoising operation)

在指纹特征提取中，结合方向图和图像局部灰度方差对指纹图像进行分割，然后再进行阈值分割去处边缘效应得出较好的分割结果。(In the fingerprint feature extraction, the combination of pattern and image local variance of gray-scale fingerprint image segmentation, and then conducted threshold segmentation edge effects come to a better place for the segmentation results.)

基于图像的条形码识别程序（识别EAN13码），只要条形码的背景部分是纯色，程序就能有相当强的鲁棒性。(Image-based bar code recognition program (recognize EAN13 code), as long as the background of the bar code is solid, the program can be quite strongly robust.)
