添加一个视频背景的分段视频

一个简单的半透明动画程序。在背景图片上进行像素提取混合，形成半透明效果-a simple translucent animation process. The background image pixels on the extraction of mixed form translucent effect

利用数字水印技术能够对数字作品实现有效的版权保护。目前的数字水印技术大多都是针对多媒体数据。但是在地理信怠系统中除了橱格数据外, 还存在大的矢童数据。目前的数字水印算法仅仅能满足橱格数据, 无法满足在矢童数据中嵌入水印的需求。本丈在分析数据特汽的基础上, 在矢童数据的频城提出了一套行之有效的数字水印算法。-The use of digital watermarking technology for digital works to achieve an effective copyright protection. At present, most of the digital watermarking technology are targeted at multimedia data. However, in the geographical letter except idle system cabinet grid data, there are still a big child vector data. At present, only the digital watermarking algorithm can satisfy the cupboard grid data, unable to meet the child in the vector data embedded watermark needs. Zhangting data in the analysis of this special steam on the basis of the data in the frequency of vector Tong City proposed a set of proven digital watermarking algorithm.

理想低通滤波,最后显示处理结果. 直接解压后将图片和程序放在同一个文件夹里.-ideal low-pass filter, the final results showed. Photo will be directly extracted and procedures on the same document folder.
