Instructors: Francois-Xavier Thomas and Roy Biswas DXOMARK Image Labs
Level: Introductory
Prerequisites: Basic image and signal theory
Benefits:
This course enables the attendee to:
- Get an overview of HDR- formats in video and photo in the industry.
- Understand existing standards and recommendations relative to HDR formats.
- Review methods for HDR image quality evaluation.
- Get practical experience with viewing HDR content and testing HDR enabled devices.
Course Description:
Modern cameras—especially smartphones—offer the capability to capture videos and photos in HDR formats by default. For end-users, these formats hold great potential to enhance the visualization experience of captured content on supported displays. This course provides an overview of why and how HDR format contents are produced, and then deep dives into the image quality evaluation of such content. A review of key concepts (existing color spaces, display/scene referred, environment and viewing conditions) is provided. The instructors review useful objective measurements and discuss the challenges of perceptual evaluation methods. The course mixes theoretical presentation with a practical hands-on session.
Intended Audience: Engineers or researchers working with visual content (images and video), including camera design, image processing, camera tuning and testing.
François-Xavier Thomas is an engineer at DXOMARK Image Labs working in designing lab protocols and measurement software to quantify imaging systems performance. He’s part of the team of engineers building the Analyzer suite of hardware and software tools which is used both internally by DXOMARK, as well as by imaging labs in other companies worldwide to assess the performance of their camera systems. Graduated from Télécom ParisTech in 2013 with a MSc in Computer Science, Image & Signal Processing, he’s been particularly active in the topics of geometrical/distortion calibration, noise & colour science as well as HDR (High Dynamic Range) technologies.
Roy Biswas holds a PhD in color science and specializes in display metrology and psychophysical experimentation. He is a member of the CIE TC1-100 and the ICDM color metrology subcommittee. Before joining DXOMARK as a color scientist, he worked for Renault and HP, Inc., where he filed for four patents and published multiple papers. His current area of interest lies in HDR video tone mapping, video and image color management, ICC workflows, and psychophysical testing of user preference toward imaging algorithms.
