Recent projects

AR-DAVID

AR-DAVID is a video quality dataset that captures how distortions due to display technologies (e.g, waveguide non-uniformity) are going to be seen on an optical see-through AR display. We found a simple blending of the environment and display light cannot predict the visibility of distortions.

elaTCSF: A Temporal Contrast Sensitivity Function for Flicker Detection and Modeling Variable Refresh Rate Flicker

elaTCSF is a temporal contrast sensitivity model that can predict the visibility of a flicker, such as a flicker found in variable-refresh-rate OLED and LCD displays.

ColorVideoVDP

ColorVideoVDP is a differentiable image and video quality metric that models human color and spatiotemporal vision. It is targeted and calibrated to assess image distortions due to AR/VR display technologies and video streaming, and it can handle both SDR and HDR content.
