EVENT-CLASS: Dataset of events in the classroom

Abstract

This work-in-progress presents a dataset of 360degree videos, called EVENT-CLASS, with associated characteristics in the context of tele-education. The sequences (video and audio) have been captured considering several environments, lighting conditions, acquisition perspectives, and cameras, enriching the dataset. EVENT-CLASS will be helpful for numerous applications related to tele-education, including quality assessment tests, and with the aim of improving the immersive experience of remote users thanks to the detection of relevant events that happen in the class. In this sense, this paper presents preliminary results of using transfer learning for person detection in 360degree scenes, based on Detectron2, and provides insights on the influence of applying it to equirectangular projection and over the viewport. Ongoing works will allow to include more videos and ground-truth annotations to the dataset.
