ST_pub
- This a research (and didactic) oriented toolbox to explore the PROSAC algorithm. The functions are reasonably well documented and there is a directory containing examples to estimate lines and homographies in presence of outliers. However a previous
Logistic
- ：提出了一种新的基于混沌映射与排序变换的图像加密算法。混沌序列具有容易生成、对初始条件敏感以及具备白噪声的统计特性等优点。该算法利用混沌映射对初值的敏感性和伪随机性，通过对生成的混沌序列排序来得到图像置乱的地址变换码，由于排序的不规则性，因此新的混沌图像置乱算法具有较强的保密性能。通过对该算法的置乱性能分 析并进行仿真实验，结果表明，新算法具有良好的图像加密性能。-his paper presents a new encryption algorithm based on chaotic m
Semi-fragile-spatial-watermarking
- 提出一种基于图像认证的半脆弱数字水印算法。该算法具有较好的自适应性，采用改进的低通滤波器，根据人眼的分辨能力设定 梯度阈值。实验结果证明，该算法对常规图像处理操作具有较强的鲁棒性，能够抵御JPEG顶级有损压缩，同时对于恶意篡改攻击(擦除、扭曲、挤压、光照等操作)表现出脆弱性，可检测出篡改的痕迹和类型。 -A semi-fragile watermark algorithm for image authentication is proposed, which has adaptabilit

- 提出了一种基于灰度图像的二维中值滤波算法。该算法每次只考虑滑动窗中移入的新数据,并充分利用了相 邻象素间的相关信息,避免了传统算法因排序所需的大量数据比较。该算法比较次数仅与窗口行或列尺寸有关,比传统方法 在处理速度上有较大提高-2D median filtering algorithm based on gray-scale images. The algorithm is time to consider a sliding window to move the new data,
mark2010estimate
- 实现一种绝对值排序的数字图像水印算法，对于频域系数进行排序然后设计新的检测器-An absolute value of the sort of digital image watermarking algorithm, to sort then design a new detector for frequency-domain coefficients
huffman
- 功能：用huffman tree去编码一个文档 算法：记录每次排序前的顺序从而构建树结构，用排序前位置为1记录各个节点-function:Encoding a document using huffman tree algorithm:records before each sort order to build the tree structure, sorted former position as a record of each node
detectSurface
- 针对摸个引用，能够分离有限元模型的表面。-It can be useful to separate the surface of a finite element model for certain applications such as fatigue analysis. For example, if cracks are known to initiate on the material surface, then the inclusion of sub-surface element
quikesort
- 一个快速排序的算法及实现过程，也实现了真正排序的过程。-A quick sort algorithm and the realization of the process, but also the realization of a real process of sorting.
