- 基于小波零树特性的视觉感知度模型的优化方案, 给出了两种水印算法: 一种算法嵌入的是高斯序列水印, 通过相关检测实现盲检测 另一种算法嵌入的是二值图像水印, 水印的提取是非盲提取。这两种算法在所有重要小波系数( 包括最低频系数) 中嵌入水印, 以达到最大化水印嵌入量的目的, 并结合感知度模型在水印的透明性和鲁棒性之间实现了较好的平衡, 对于常见的图像处理操作, 特别是对于JPEG 和小波压缩均有较好的鲁棒性。-based on wavelet zerotree visual perception

- 经过几个月的设计和开发，计算机图书馆管理系统基本开发完毕。其功能基本符合需求，能够完成书籍录入，借阅，查询、统计、用户管理。并提供部分系统维护功能,使管理员能够方便进行数据添加和修改、数据删除等功能。 但是由于毕业设计时间较短，所以该系统还有许多不尽如人意的地方，比如联机文档比较少，用户界面不够美观，出错处理不够等多方面问题。这些都有待进一步改善。 几个月的毕业设计，使我提高了实际操作能力，从以前的理论上升到实践，从感性认识上升到理性认识，真正做到学有所用，懂得先要发现问题，分析问题，解决问
