ZURICH, May 4, 2017 — The facial appearance of actors can now be transformed during a live performance using a projector-based illumination system that tracks an actor’s facial movements and changing expressions without the need for facial markers. A key challenge of live dynamic augmentation of human faces via projection is latency — i.e., when an image is generated according to a specific pose, but displayed on a different facial configuration by the time it is projected. The Makeup Lamp, developed by a team at Disney Research, reduces latency during every step of the process from capture,...Read full articleRelated content from Photonics MediaARTICLES3D-Printed Microlenses Correct Color Distortions in Small-Scale ImagesResearchers from the University of Stuttgart used a 3D-printing process called two-photon lithography to make highly precise lenses that are just a few micrometers in size and that reduce chromatic...Photonics Spectra August 2021 IssueBalluff to Establish Budapest Office: Vision BriefsMachine vision technology company Automation Technology (AT) promoted Nina Claaßen to head of marketing.
