Selected Publications

In this paper we introduce the problem of saliency ranking, which arises from the observation that observers may not agree upon what is salient. We propose models, metrics and analysis associated with this problem.

In this paper we propose a gating mechanism that receives recurrent feedback from upstream feature activations. This produces significant improvements for recognition performance.

We consider visual saliency modeling including gaze prediction and salient object segmentation. This discourse reveals a number of high-level considerations relevant to deep-learning models for visual saliency prediction.
In CVPR, 2016

In this paper we present a definition for visual saliency grounded in information theory. This definition reveals strong ties between disparate concepts including scale-space theory, bilateral filtering, random walks and other phenomena.
In NIPS, 2015
