JPEG backward compatible coding of omnidirectional images
Omnidirectional image and video, also known as 360 image and 360 video, are gaining in popularity with the recent growth in availability of cameras and displays that can cope with such type of content. As omnidirectional visual content represents a larger set of information about the scene, it typically requires a much larger volume of information. Efficient compression of such content is therefore important. In this paper, we review the state of the art in compression of omnidirectional visual content, and propose a novel approach to encode omnidirectional images in such a way that they are still viewable on legacy JPEG decoders.
