An Algorithm of Extracting I-Frame in Compressed Video
College of Software Engineering, Lanzhou Institute of Technology, Lanzhou, Gansu, China
The MPEG video data includes three types of frames, that is: I-frame, P-frame and B-frame. However, the I-frame records the main information of video data, the P-frame and the B-frame are just regarded as motion compensations of the I-frame. This paper presents the approach which analyzes the MPEG video stream in the compressed domain, and find out the key frame of MPEG video stream by extracting the I-frame. Experiments indicated that this method can be automatically realized in the compressed MPEG video and it will lay the foundation for the video processing in the future.
Key words: MPEG / key frame extraction / I-frame / DCT
