Title
(EN) Gaze direction-based adaptive pre-filtering of video data
Abstract
(EN)

A multi-layer low-pass filter is used to filter a first frame of video data representing at least a portion of an environment of an individual. A first layer of the filter has a first filtering resolution setting for a first subset of the first frame, while a second layer of the filter has a second filtering resolution setting for a second subset. The first subset includes a data element positioned along a direction of a gaze of the individual, and the second subset of the frame surrounds the first subset. A result of the filtering is compressed and transmitted via a network to a video processing engine configured to generate a modified visual representation of the environment.
