Description: 由于在Windows2000下右键点击RIFF (*.avi,*.wav) 类型的文件，在摘要里没有该文件的具体信息，所以我就编了一个小程序，用来显示该类型文件的信息。具体信息主要包含视频流和音频流信息。视频流信息主要有:(1)Total frames (2)Frame rate (3)Codec (4)视频的宽度和高度等。音频信息主要有:(1)音频的格式 (2)单声道还是立体声 (3)采样频率等。-in Windows2000 Right click RIFF (*. avi, *. wav) file types, in a summary of the document was not specific information, so I compiled a small program used to indicate the type of document information. Specific information mainly includes streaming video and audio streams of information. Video streams of information are : (1) Total frames (2) Frame rate (3) Codec (4) video on the width and height. Major Audio Information : (1) Audio format (2) mono or stereo (3) sampling frequency.

Description: 这是外国朋友David写的一个以小猪为主角的平台游戏，画面流畅，极富动感。但由于其采用的\"固定逻辑帧速率\"的游戏引擎与声音引擎有所冲突，所以就没有加入音乐。游戏原本只提供四关，我制作了其中的七个关卡。-David foreign friends to write something for a player platform games, face smooth, very exciting. But because of its use of the "Fixed logic frame rate" of the game engine with sound engine conflict, it would not add music. The game was originally provided only four hurdles, I produced one of the seven points.

Description: 视频拼接Filter。将2路视频拼成一路输出。非压缩的RGB和YUV格式，输入端格式必须一致，第一路视频决定输出的帧率。写这个Filter主要是为了把两路视频采集到一个文件中，如果只是要把多路视频合成后显示的话，建议使用VMR-9-Video Mosaic Filter. Will be two video output as guarding our way. Non-compressed RGB and YUV format, input must be consistent format, the first video output frame rate decision. Filter wrote this mainly to the two video collection to a document, If only multi-channel video should Synthesis shows the proposed use of VMR-9

Description: For many embedded systems USB seems to be a good solution for data acquisition
modules - as USB supports a frame rate of 1 ms which is fast enough for many
feedback control applications. The problem now is that USB is currently only
supported by Windows 98 and updates of Windows 95. The design of the USB host
controller again emphasizes the possibilities using USB in an embedded System:
Once the USB communication is established, the host controller can work in the
background using DMA-memory transfers - accompanied with a synchronous
interrupt every millisecond, a real time feedback control system is easily
established.-For many embedded systems USB seems to be a good solution for data acquisitionmodules- as USB supports a frame rate of 1 ms which is fast enough for manyfeedback control applications.

Description: This project deals with the tracking and following of single object in a sequence of frames
and the velocity of the object is determined. Algorithms are developed for improving
the image quality, segmentation, feature extraction and for deterring the velocity. The
developed algorithms are implemented and evaluated on TMS320C6416T DSP Starter
Kit (DSK). Segmentation is performed to detect the object after reducing the noise from
that scene. The object is tracked by plotting a rectangular bounding box around it in
each frame. The velocity of the object is determined by calculating the distance that the
object moved in a sequence of frames with respect to the frame rate that the video is
recorded. The algorithms developed can also be used for other applications (real time,
object classi cation, etc.).

Description: Abstract—Based on the observation that low-frequency DCT
coefficients of an image are less affected by geometric processing,
we propose a new blind MPEG-2 video watermarking algorithm
robust to camcorder recording. Both the embedding and
extraction of the watermarks are done in the compressed domain.
The mean of the low-frequency DCT coefficients of the video is
temporally modulated according to the information bits. To
reduce complexity, we embed watermark in the prediction error
signals of the B-frames. Experimental results show that the
proposed scheme achieves high video quality and robustness to
camcorder recording, trans-coding, frame-rate conversion, and
geometric attacks on common test videos.
