Description
Summary:First-person action recognition is a recent problem in computer vision, where an observer wears body cameras to understand and recognize actions from the captured video sequences. Technological advances have made it possible to offer small wearable cameras that can be attached onto bike helmets, belts, animal halters, among other accessories. Examples of potential applications include sports, security, healthcare, visual lifelogging, among others. In this paper, we propose a novel approach to first-person action recognition that consists in encoding video appearance, shape and motion information as visual rhythms and describing them through texture analysis. Experiments are conducted on the DogCentric Activity and JPL First-Person Interaction datasets, showing accuracy improvement over the baselines.
