matlab产生均匀 高斯 锐利等分布并画出直方图(using matlab to get random)

本程序为抗JPEG压缩的半脆弱性彩色图像数字水印，主要原理为DCT转换和DCT系数比较法，内含5中攻击仿真测试以及GUI界面，测试环境为MATLAB2009a，系本人2013年本科毕业设计(The procedures for the anti-JPEG compression semi-fragile color image watermarking, the main principle is the DCT transform and DCT coefficients comparative law, including five in the attack simulation testing and GUI interface, the test environment is MATLAB2009a, Department I graduated design 2013)

一种基于奇异值分解的数字水印技术，这是一篇很经典的文章，再此文章之后，基于svd的水印技术大量出现(a digital watermarking technologybased on Singular value decomposition , which is a classic article, and then, after this article, the watermarking technique based on large numbers of svd)

This is a MATLAB implementation of the SIFT keypoint detector and descriptor (do_gaussian: generate Gaussian scale space of input image do_diffofg: generate Difference of Gaussian (DoG) scale space do_localmax: local extrema as the potential keypoints do_extrefine: refine the keypoints by discarding the ones with low contrast and along an edge do_orientation: compute the orientation of a support region of keypoint do_descriptor: compute the descriptor of a keypoint based on image gradients. do_match: match two images based on the nearest neighbor principle and spatial consistency. do_sift: generate the SIFT descriptors for a given input image. It basically s all the functions above. )

以Rossler方程!Duffing方程和Vanderpol方程为例,应用Matlab仿真工具进行模拟, 并对仿真结果作了简要说明和讨论,其中的示例对混沌研究和教学有一定的意义.(To Rossler equation! Duffing equation and the van der Pol equation as an example, the application of Matlab simulation tool for simulation, simulation results and a brief description and discussion, including examples of research and teaching on the chaos has a certain significance.)
