Recent years have seen a new uptake in immersive media and eXtended Reality (XR). And due to a global pandemic, computer-mediated communication over video conferencing tools became a new normal of everyday remote collaboration and virtual meetings. Social XR leverages XR technologies for remote communication and collaboration. But in order for XR to facilitate a high level of (social) presence and thus high-quality mediated social contact between users, we need high-quality 3D representation of users. One approach to providing detailed 3D user representations as new immersive media is to use point clouds or meshes, but these representation formats come with complexity on compression bitrate and processing time. In the example of virtual meetings, compression has to fulfill stringent requirements such as low latency and high quality. As the compression techniques for 3D immersive media steadily advance, it is important to be able to easily compare different compression techniques on their technical and visual merits in an easy way. The proposed demonstrator in this paper is a visualization tool that helps assessing the visual quality of a 3D representation employing various coding schemes. The complete end-to-end rendering/encoding chain can be easily assessed, allowing for subjective testing by showing the differences between the selected encoding parameters. The tool presented in this demo paper offers an improved and easy visual process for the comparison of encoders of immersive media. |
