>> *ABSTRACT*
>> Humans have the remarkable ability to follow the gaze of other people to
>> identify what they are looking at. Following eye gaze, or gaze-following,
>> is an important ability that allows us to understand what other people are
>> thinking, the actions they are performing, and even predict what they might
>> do next. Despite the importance of this topic, this problem has only been
>> studied in limited scenarios within the computer vision community. In this
>> talk I will present a deep neural network-based approach for
>> gaze-following. Given an image and the location of a head, our approach
>> follows the gaze of the person and identifies the object being looked at.
>> Furthermore, I will also introduce GazeNet, a deep neural-network to
>> predict the 3D direction of a person's gaze from the full 360 degrees. To
>> complement GazeNet, I will present a novel saliency-based sampling layer
>> for neural networks, the Saliency Sampler, which helps to improve the
>> spatial sampling of input data for an arbitrary task. Our differentiable
>> layer can be added as a preprocessing block to existing task networks and
>> trained altogether in an end-to-end fashion. The effect of the layer is to
>> efficiently estimate how to sample from the original data in order to boost
>> task performance. For example, for the gaze-tracking task in which the
>> original data might range in size up to several megapixels, but where the
>> desired input images to the task network are much smaller, our layer learns
>> how best to sample from the underlying high resolution data in a manner
>> which preserves task-relevant information better than uniform downsampling.
