2. JPEG
• The Joint Photographic Experts Group (JPEG)
– Working group of the International Standardization Organization
(ISO) and the International Electrotechnical Commission (IEC) –
ISO/IEC JTC1/SC29/WG1
– “Joint” refers to the additional collaboration with the International
Telecommunication Union (ITU)
• Compression standards
– JBIG-1 & JBIG-2
– JPEG
– JPEG-LS
– JPEG 2000
– JPEG XR
– AIC (Upcoming)

3. Why JPEG 2000
• The incentive behind the development of the JPEG 2000 system
was not just to provide higher compression efficiency than the
baseline JPEG system, but also to provide a rich set of features:
– Improved compression efficiency
– Lossy to lossless compression
– Multiple resolution representation
– Embedded bit-stream, including progressive decoding and signal-to-noise (SNR)
scalability
– Tiling
– Region-of-interest (ROI) coding
– Error resilience
– Random codestream access and processing
– Improved performance to multiple compression/decompression cycles
– Flexible file format

12. Our Product
• ETRO designed/wrote a software package that:
– Delivers JPEG 2000 Part 1 compatibility
– Delivers JPEG 2000 Part 10 (JP3D) compatibility
• It is the official JPEG 2000 reference software of JP3D
• Currently the ONLY available software package that has JP3D functionality
– High and competitive compression performance
– Simple design
• This makes it also interesting to hardware chip designers and researchers
– Easy to use, modify, learn from
• This makes it also interesting to hardware chip designers and researchers
– Originally intended for internal research and as reference
software for the JPEG 2000 Part 10 standard

13. Our Problem
• Numerous requests from companies and academic
institutions for our code (often in research context)
• Non-commercial vs. commercial use policies?
– Can we create some kind of revenue?
• How to provide access to the code? (NDA?)
• Licenses?
• Warranties?
• Support?
