Description: Wavelets have widely been used in many signal and image processing applications. In this paper, a new
serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet
transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline
architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is
done using a tree of carry save adders to ensure the high speed processing required for many applications.
The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis
reveals that the proposed architecture, implemented using current VLSI technologies, can process a
video stream in real time.-Wavelets have been widely used in many sign al and image processing applications.

Description: 目前绝大部分视频数字水印系统是将一个64位-128位的条码嵌入到视频中，而本软件最大特点是可将用户任意指定的一幅120x120的
黑白图片(如电子印章)隐藏在一段视频流中。这样做的优点是给用户提供了最大的直观性，同时由于偶们嵌入的是一幅图片而不是一组确定的数字，因此在视频被重编码为mpeg4低分辨率格式、信息大量丢失的情况下，仍可以通过人眼识别出已经非常模糊的图片。-At present, the vast majority of video digital watermarking system is a 64-bit-128 barcode embedded into the video, which is the biggest characteristic of this software can be arbitrarily designated a user 120x120 black-and-white images (such as electronic seals) hidden in a section of video stream. The advantages of doing so is to provide users with the most intuitive, at the same time as a result of embedded偶们is a picture rather than a group to determine the figures, so the video was re-encoding for mpeg4 low-resolution formats, the information a large number of missing cases Under the adoption of the human eye can still identify the picture is very fuzzy.

Description: 人脸识别技术可以应用于基于网络的身份认证，我们实现了基于WebCam的人脸识别与跟踪系统。本文以WebCam采集的视频流为数据源，截取视频流中的单帧图像，通过转换色彩空间、人脸肤色建模、后处理操作和人脸定位算法实现了人脸检测，并以此为基础实现了在视频流中对于人脸的跟踪。试验结果表明，我们所实现的人脸识别算法适用于近距离人脸的检测，可以应用于基于WebCam的身份认证。-Face recognition technology can be applied to Web-based authentication, we realize the face recognition based on the WebCam with the tracking system. This paper collected WebCam video stream for the data source, the interception of the video stream in the single frame images, through the color space conversion, color facial modeling, post-processing operation and Face Location Algorithm for Face Detection realized as the basis for the realize in the video stream for tracking human faces. The experimental results show that we realize the face recognition algorithm applied to close-up face detection, can be applied to authentication based on the WebCam.

Description: 头一段时间做jmf程序，要把截获的视频流，潜入到网页中，并播放；在网上找了很多例子，是弹出frame框形式的，没有做成嵌入到applet里面，自己做了一个嵌入到applet里面的。也就是把播放器嵌入到applet里面，而不是弹出一个Frame框，并且定义了两个按钮；一个启动，一个停止；以下是源码；
解压码是:xuedijiujiu
这是个客户端applet程序程序，实现视频的接受和播放；服务器端可以用JMStudio来辅助调试；
程序仅供研究
