- Hi, I am doing a project on video compression using the latest
- International standard (draft), the MPEG algorithm. Rather, I am
- first making a thorough study of the MPEG techniques and as time
- permits try to make a software simulation of the building blocks
- of the MPEG encoder. I am working on a Sun Sparc 4 workstation.
-
- I am a Computer Science grad student in Wayne State University, Detroit.
-
- MPEG means MOVING PICTURES EXPERT GROUP of the joint ISO-IEC committee
- which is developing a world-wide video coding standard (at 1.5 Mbit/s).
- The other group is the JPEG for still image compression.
-
- The purpose of this letter is for asking for help in the following
- directions. Anybody out there have any sources?
-
- 1. I am looking for an image sequence (video sequence preferably)
- 512x512 (or 256x256) gray-scale, 8 bit/pel quantized, suitable
- for use on Sun Sparc 4 station terminal.
-
- Actually, if anyone knows or has a good test sequence for the
- simulation of MPEG, it would be best.
-
- 2. Although I got quite some info from various tech. papers,
- especially from Proc., SPIE about MPEG and various motion-compensated
- prediction/interpolation encoder development and various motion-
- estimation techniques, and an overview on MPEG as well, I need more
- info for the exact implementation details for the encoder. (esp.
- for software simulation)
-
- 3. Any info on software implementation techniques or algorithms
- for MPEG simulation. Since the simulation of the whole encoder
- is quite a involved and big project, I was thinking of starting
- with the important building blocks, like Motion Estimator, for
- the MPEG.
-
- Actually, last semester I could simulate the still image compression
- standard, the JPEG, since it is much easier than MPEG moving-picture
- compression.
-
- I did try to ftp into isy.liu.se for some image sequences. I was
- not able to convert from the .imf format. When I went into the
- vi editor to strip the header from the .imf file, it said line
- too long!???
-
- So, I appreciate any help regarding the above directions.
- At least you could send me any sources you know!
-
- Thanks a lot,
- Bascar.
