利用小波熵自适应去噪并求出各层熵值（绝对值表示） 及权重，自写论文(Using wavelet entropy adaptive de-noising and the obtained layers entropy (absolute value) and weight, since writing papers)

经典的图像处理常用图片，包括Lina，Barbana, Cameraman(Classic image processing commonly used pictures, including Lina, Barbana, Cameraman)

采用National Instruments 视觉算法库，雷赛运动控制卡，映美精相机 检测手机LOG(Using National Instruments vision algorithms library, Lemire motion control card, Imaging camera detects the phone LOG)

：数字水印将感觉不到的信号嵌入到声频、视频和图像中以实现不同的目的。例如: 添加标题和版权保护。首先介绍 了有关数字水印的基本原理、重要属性及其主体框架。然后,将数字水印按不同角度划分为不同种类。讨论了各种各样的数 字水印算法以及数字水印在不同领域的应用,并简要介绍了对数字水印的攻击。最后,给出了数字水印当前的研究现状和发 展形式及前景。(: Digital watermark embedding imperceptible signals to the audio, video and images to achieve different purposes. Example: Add a title and copyright protection. Firstly, the basic principle about digital watermarking, and the main framework of the important attributes. Then, the digital watermark according to different angles into different types. Discussed a wide range of digital watermarking algorithms and digital watermarking applications in different fields, and a brief introduction of the digital watermarking attacks. Finally, the digital watermark of the current situation and development in the form of research and prospects.)

提取图形的七阶不变矩，简单易行，利用求得特征矩进行图像的识别(It is simple and easy to extract the seven order moment of the graph, and the image is identified by using the characteristic moment.)

人类视觉系统的matlab工具箱，包括亮度掩膜，对比度掩膜和对比度灵敏度函数的实现。是学习人类视觉系统非常好的入门材料。()
