[visionlist] Optica Color Technical Group Webinar – Register Now

[Jingyi He]

Dear All,


I’m pleased to invite you to an upcoming Optica *Color* Technical Group
Webinar:


*Date:* 28 April 2025
*Time:* 12:00 - 13:00 Eastern Daylight/Summer Time (US & Canada) (UTC
-04:00)
*Speaker: *Rafał K. Manituk from University of Cambridge
*Topic:* Color VDP: A Visual Difference Predictor for Image, Video and
Display Distortions


Assessing the visual quality of color images and videos is a key focus in
fields such as computer graphics and computer vision. However, it is
fundamentally challenging to develop reliable metrics for perceptual
differences, as color appearance depends on spatial and temporal contexts
in complex ways. In this webinar hosted by the Color Technical Group, Rafał
Mantiuk will present his recent work on ColorVideoVDP, a quality metric for
video and images that models how the human visual system processes
luminance and color over space and time.


This metric is built on psychophysical models of chromatic spatiotemporal
contrast sensitivity and cross-channel contrast masking, and it considers
viewing conditions along with the geometric and photometric properties of
displays. ColorVideoVDP supports various applications requiring
spatiotemporal assessment of luminance and color distortions, including
video streaming, display design, visual comparisons, and perceptually
guided quality optimization. This webinar will be especially relevant for
researchers studying low-level processing in human color vision and for
those using these metrics to evaluate the quality of displayed content.

Looking forward to your participation!
