Workshop Topics
Optics, Scenes and Sensors. Exploring the limits of HDR capture
Ricardo Motta, moderator.
There is little doubt that we live in an HDR world - almost no scene is void of shadows or highlights, and a number of schemes have emerged to properly capture huge contrasts. Development in image sensors has led to ever increasing claims on their HDR capture ability, well above 120 dB sometimes, yet there is evidence that this above the range what many natural scenes contains, and what optics can imprint on the sensor surface. What gives? What are the limits? In the panel we will hear experts on such limits and how to measure them, and work together to address these issues in a workshop.
Unified Metrics for Diverse Displays
Tim Drabik, moderator
How can we formulate HDR performance standards that encompass display technologies in a unified manner? What challenges are presented? How well can performance metrics comport with subjective image quality? Panelists will discuss dynamic range figures of merit as well as the interplay among dynamic range performance and other attributes of underlying display technology such as viewing-angle variations, frame rate, motion artifacts, and color gamut.
Tone-mapping for High Dynamic Range Imagery
Greg Ward, moderator
Tone-mapping is the task of modifying the dynamic range of an image source to match a destination, which can involve either compression or expansion. Many methods have been suggested for both directions, and issues abound. Panelists will present their favorite techniques and discuss open questions with the audience as an introduction to the topic and the afternoon workshop.
