图像拼接原代码，ＶＣ＋＋，图像拼接在制作全景图的过程中具有重要作用。对多幅图像进行特定模式投影后, 用约束的相位相关度法求取水平垂直偏移量,然后寻找最佳缝合线,实现图像拼接, 最后采用多分辨率算法对全图进行拼接处理去除曝光差异和鬼影。 整个过程用VisualC++加以实现,实验结果验证了算法的有效性。

SLl0算法是一种压缩感知稀疏重构的新算法，通过利用高斯函数等光滑函数来逼近压缩感知中的0范数优化问题，将NP问题转化为光滑凸优化问题。根据本人测试，SL0算法计算效率显著高于传统的OMP、BP等算法，同时具有较好的计算精度，不过对噪声的容忍度略差。

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e
