Generalizable Embodied Foundation Model

Thursday, 30 January, 2025 - 14:00 to 15:00

In this talk, we will start from the fundamental question of what is, how to measure, how to improve the generalization ability of deep neural networks, especially on the out-of-distribution generalization ability, where the test data distribution differs from the training data distribution. Then, we will demonstrate how...

Socially assistive robots: we can do better (online talk)

Thursday, 21 November, 2024 - 14:00 to 15:00

Speaker bio: Shelly Levy-Tzedek is an associate professor and the director of the Cognition, Aging & Rehabilitation Laboratory at Ben Gurion University. Prof. Levy-Tzedek completed her undergraduate studies, summa cum laude, at UC Berkeley, where she won the Bioengineering departmental citation medal. At the...

Modelling contrast matching across luminance levels [practice talk]

Monday, 21 October, 2024 - 16:00 to 17:00

The study investigates the modelling of contrast matching functions (SCMF) across various luminance levels, addressing the nonlinear behaviour of the human visual system in perceiving suprathreshold contrasts. Using a comprehensive dataset of contrast matching experiments involving younger and older observers, the research...

Learning-based Material Appearance Acquisition and Modeling for Predictive Rendering

Thursday, 24 October, 2024 - 14:00 to 15:00

Recent developments in computer graphics, and particularly within predictive rendering, enable highly realistic simulations of object appearances. Though physically-based reflectance (PBR) models offer widespread utility, measured material reflectance data yields significantly superior accuracy through the direct empirical...

Tracking eye position and gaze direction in near-eye volumetric displays [practice talk]

Thursday, 17 October, 2024 - 14:00 to 15:00

Near-eye volumetric displays, showing multiple focal planes, require knowledge of the accurate position of the nodal point of the eye to correctly render a 3D scene. This is because pixels seen through multiple planes must be accurately aligned with the eye’s visual axis to ensure consistency across focal planes. While...

[CANCELLED] Color-Accurate Camera Capture with Multispectral Illumination and Multiple Exposures [practice talk]

Thursday, 10 October, 2024 - 14:00 to 15:00

[CANCELLED] Cameras cannot capture the same colors as those seen by the human eye because the eye and the cameras’ sensors differ in their spectral sensitivity. To obtain a plausible approximation of perceived colors, the camera’s Image Signal Processor (ISP) employs a color correction step. However, even advanced color...

Understanding color and gloss perception with deep neural networks

Thursday, 19 September, 2024 - 14:00 to 15:00

In daily life, visual properties such as color and gloss are crucial for identifying and distinguishing objects around us. I will present two research projects that investigated the mechanisms of color and gloss perception using deep neural networks (DNNs). In the first project, we used DNNs to explore why we have higher...

Trustworthy Data Visualization

Thursday, 11 July, 2024 - 14:00 to 15:00

When can we trust a data visualization to communicate the same message to different groups of people? Most visualization guidelines are untested and biased toward one designer's viewpoint. What scientific evidence can we bring to visualization, and what methods can we use to ensure that visualizations are working for...

The effect of viewing distance and display peak luminance - HDR AV1 video streaming quality dataset

Thursday, 13 June, 2024 - 14:00 to 15:00

While it is well recognized that the visibility of distortions is affected by the viewing distance and display peak luminance, very few datasets control those conditions, and also few video quality metrics can account for them. To address this gap, we collected a new video quality dataset, HDR-VDC, which captures the...
