Advantages to Educators of Jpeg 2000
SCHEMA JUNE 2004

2. Welcome to the world of Jpeg 2000 image compression file format!
SUMMARY:
What is Jpeg 2000
Is Jpeg 2000 already a “standard” file format?
Status of the technology
Alinari benchmarking study overview
Benefits for educators and in the school sector
Future work
Q&A

3. What is Jpeg 2000?
A Lossless compression technology
Promoted by the Joint Photographic Expert Group (JPEG) and by Int. Standards Organization (I3A)
Jpeg uses Discrete Cosine Transform (DCT) while J2K uses wavelets (signal decomposes into different little waves)

4. It supports new features such as:
Error Resiliance
Region of Interest
Watermarking and IPR
Metadata
ICC color profiling
File history

5. Is Jpeg 2000 already a standard?
The answer is YES! In fact already commercial companies like Apple, Algovision-Luratech, Adobe, Pegasus, Aware and LeadTools are supporting it…
Moreover content providers like Alinari Photo Archive have began to save their valuable high quality digital assets into Jpeg 2000
Prediction for a full Jpeg 2000 acceptance success? Once the major Internet browsers will include it as a default plugin

6. Status of the Technology:
Below some examples that show the good progress that this codec has produced in the last 2 years of R&D: 1/3

14. Advantages for Educators and Students 1/2:
Lossless (no quality loss)
Compression rate much higher than Jpeg
Compression much more robust (error resiliance)
Very useful compression solution to enlarge on the fly details of a given image
Easier to handle (open, send and manage, overall)

15. Advantages for Educators and Students 2/2:
Working with 1 single format (Jpeg 2000 will replace all other formats soon!!!)
Teachers and students will be able to work with high resolution images more easily (smaller files)
Full compatibility (jpeg 2000 reader can open jpeg files)
Secure, standard and robust technology

16. Future work: Adopting it into a larger scale
Working on additional functions and “bells”
