对于一维波的压缩感知重构算法，使用OMP算法，重构效果良好，供参考 (For the one-dimensional wave of compressed sensing reconstruction algorithm, using OMP algorithm to reconstruct the effect is good, for reference)

罚函数法是将有约束最优化问题转化为求解无约束最优化问题。在此给出罚函数法的Matlab源程序。(Penalty function method is a constrained optimization problem into solving unconstrained optimization problems. This gives the penalty function in Matlab source.)

本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力(failed to translate)
