Exogenous cues and visual confidence

Hemifield asymmetry in the potency of exogenous auditory and visual cues

Neurologically normal subjects misperceive the midpoints of lines (PSE) as reliably leftward of veridical center, a phenomenon known as pseudoneglect. This leftward bias reflects the dominance of the right cerebral hemisphere in deploying spatial attention. Transient visual cues, delivered to either the left or right endpoints of lines, modulate PSE such that leftward biases are increased by le...

Modeling Audio and Visual Cues

Audio-visual event detection aims to identify semantically defined events that reveal human activities. Most previous literature focused on restricted highlight events, and depended on highly ad-hoc detectors for these events. This research emphasizes generalizable robust modeling of single-microphone audio cues and/or single-camera visual cues for the detection of real-world events, requiring ...

Eulerian Opinion Dynamics with Bounded Confidence and Exogenous Inputs

The formation of opinions in a large population is governed by endogenous (human interactions) and exogenous (media influence) factors. In the analysis of opinion evolution in a large population, decision making rules can be approximated with non-Bayesian ”rule of thumb” methods. This paper focuses on an Eulerian bounded-confidence model of opinion dynamics with a potential time-varying input. ...

Controllable Visual Cues

This project concerns the development of analytical and computational tools for the analysis of dynamic visual processes. In particular, emphasis has been given to the estimation of visual motion for the purpose of control, the estimation of shape from moving images, the estimation of spatio-temporal image statistics for visual modeling, synthesis and recognition. The project is in its final ye...
