说明： 本文提出了一种基于混沌加密的DCT域二值图像数字水印算法.该算法首先利用混沌序列将含有版权信息的有意义二值图像水印进行加密,然后利用人眼视觉系统(HVS)的特性将原始载体图像进行块分类,最后将不同强度的水印分量嵌入到不同类的图像块DCT中频系数中去.利用混沌序列对水印进行加密,使水印本身具有安全性,对数字作品进行双重保障.通过高斯噪声,椒盐噪声以及JPEG压缩和剪切等攻击试验,表明了该算法具有较好的鲁棒性.(Encryption in DCT domain is proposed. Firstly, the meaningful binary image watermark containing copyright information is encrypted by using chaotic sequence, and then the original image is classified by using the characteristics of human visual system (HVS), Finally, the watermark components with different intensities are embedded into the DCT intermediate frequency coefficients of different types of image blocks. Chaotic sequences are used to encrypt the watermark, so that the watermark itself has security and double protection for digital works. Experiments on Gaussian noise, salt and pepper noise, JPEG compression and clipping show that the algorithm has good robustness)

Face recognition is still a challenging task due to the different problems such as pose, illumination, expression and occlusions. Due to these problems, it needs an extensive research. Various face recognition techniques exists but they suffer one or the other limitations.

感知器算法
感知器算法是一种神经网络的模型，是20世纪50年代中期到60年代初人们对模拟人脑学习能力的一种分类学习机模型的称呼。当时的研究者认为它是一种学习的强有力模型，但以当时的技术无法实现非线性分类，许多实验室都放弃了感知器的研究。但其中的思想很经典，对后来的模式识别模型有很大的影响。当然，随着时代的进步，已经有很多学者提出了许多非线性的感知器改进算法，并取得良好效果，此程序主要基于Matlab来具体实现传统的感知器算法。(This program is based on Matlab to specifically achieve the traditional perceptron algorithm.)
