Advantages to Educators of Jpeg 2000 Andrea de Polo-Sam Minelli Fratelli Alinari Advantages to Educators of Jpeg 2000 SCHEMA JUNE 2004

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

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)

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

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

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)

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

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