Context

The Joint Photographic Experts Group (JPEG) committee (ISO/IEC JTC 1/SC 29/WG 1) has a long tradition in the creation of still image coding standards. JPEG performs continuous efforts to design coding standards triggered by changing market needs and technological evolutions.

Holography, an optical technique for recording and reconstructing light wavefronts, was invented by Dennis Gabor in 1948 to enhance electron microscope resolution. Unlike traditional imaging, which relies on ray-based models, holography uses interference patterns to capture and reconstruct light fields, offering high-depth resolution and accurate refractive index reconstruction. This makes it particularly valuable in fields like biomedical imaging and industrial measurement. Holography also promises to enhance the user experience in XR environments by resolving issues like the vergence-accommodation conflict, paving the way for more immersive and realistic applications.

JPEG Pleno Holography (ISO/IEC 21794-5) is the first international standard to address the efficient compression and representation of holographic content. The standard supports lossy compression of complex-valued holograms and lossless compression of binary holograms. This versatility ensures that it can cater to various applications, from holographic microscopy and tomography to holographic displays and printing.

Notwithstanding the standard JPEG Pleno Holography is a milestone for the compression of holographic content, JPEG seeks for continuous improvement of its standards and associated use case and requirements specifications. Hence, this workshop is intented to gather experts in the field and to identfy future challenges and standardization needs.
