About This Webinar
The field of hyperspectral imaging is seeing sustained growth and expansion into new applications ranging from industrial machine vision to space exploration. There has been a notable lack of standards applying specifically to hyperspectral imaging. Since 2018, the IEEE Standards Association Project 4001 (P4001) has worked to create a standard that covers unmet needs in this field. The P4001 standard is the result of the collective work of a large group including manufacturers, users, labs, and academia. The standard, now in its final stages of review, details how to specify all major aspects of the performance of a hyperspectral camera, including nonidealities such as coregistration errors.

The P4001 standard will also define camera-related metadata that will aid the analysis of hyperspectral images. The standard defines different levels of required detail for three notional use cases, which address a wide range of applications, from cost-sensitive industrial automation to high-end remote sensing. Specific camera test procedures are not mandated, but appendices outline possible ways to test a hyperspectral camera according to the standard.

The talk reviews the contents of the standard and explains the rationale behind some of the choices that have been made by the working group.

About the presenter

Torbjørn SkauliTorbjørn Skauli is professor of optical sensor and imaging technologies at the University of Oslo, Department of Technology Systems. He also works as principal scientist at the Norwegian Defence Research Establishment (FFI). Skauli has worked on many aspects of imaging systems, from crystal growth and readout electronics for detectors to field trials and theoretical studies of cameras. He has done extensive research in the field of hyperspectral imaging and has participated in numerous international research projects.

Skauli has also worked as a visiting scientist at the Defence Research Agency in the UK and at Stanford University in the US. On the side, Skauli has been extensively engaged in outreach to share with young people the joys of programming, amateur radio, and "making". Skauli has been engaged in development of the IEEE "P4001" standard for hyperspectral imaging since its inception, serving as vice chair of the working group since 2020.
