• Egocentric videos provide a rich source of hand-object interactions that support action recognition. However, prior to action recognition, one may need to detect the presence of hands and objects in the scene. In this work, we propose an action estimation architecture based on the simultaneous detection of the hands and objects in the scene. For the hand and object detection, we have adapted well known YOLO architecture, leveraging its inference speed and accuracy. We experimentally determined the best performing architecture for our task. After obtaining the hand and object bounding boxes, we select the most likely objects to interact with, i.e., the closest objects to a hand. The rough estimation of the closest objects to a hand is a direct approach to determine hand-object interaction. After identifying the scene and alongside a set of per-object and global actions, we could determine the most suitable action we are performing in each context.
