JPEG Workshop/2026 Cycle 1 IEEE SPS Chapter Initiative

Context

The advent of Artificial Intelligence is fundamentally transforming the way visual information is represented, compressed, transmitted, authenticated, and consumed. Learning-based media coding, generative AI, and machine-oriented representations are redefining the traditional boundaries of multimedia systems, while simultaneously raising new challenges related to trustworthiness, authenticity, interoperability, and regulatory compliance.

As AI becomes an integral part of media representation, international standards play a fundamental role in ensuring that emerging technologies remain interoperable, reliable, and widely deployable. Recent developments such as learning-based image and point cloud coding, coding for machines, and media authenticity frameworks illustrate how standardization is evolving to address both technical innovation and societal needs. The JPEG Committee has been leading this transformation through the development of next-generation standards such as JPEG AI, JPEG Pleno PCC, and JPEG Trust.

This workshop brings together researchers, industry experts, policymakers, and members of the international standardization community to discuss recent advances in AI-based media representation technologies and their implications for future multimedia systems.

The event is co-organized by the Portuguese Chapter of the IEEE Signal Processing Society (IEEE SPS) within the framework of the IEEE SPS Member-Driven Initiative Program.
