This talk sounds interesting (although unfortunately I might not be able to attend!)

> ABSTRACT:
> Human visual system has high visual acuity in a small region of the fovea and the photoreceptor density drops rapidly when moving away from the fovea. This requires eye movements to search for task-relevant features in the scene.  This research focuses on search strategies for visual search, specifically human subjects identifying people in cluttered scenes. We present a principled approach to the study of factors that contribute to person search. A novel video database is created that systematically tests how different parts of a person contribute towards eye-movements and person identification. One surprising finding is that a face-centered strategy does not necessarily maximize the person identification performance in human subject trials. Next, a neural network based approach is proposed to model eye movements that further improves upon the current state of the art models. Finally, a new foveated convolutional neural network is presented that leverages multiple fixations and is adaptive to available computational resources to improve the overall recognition rates.
