Abstract

This paper presents an efficient method for encoding common projection formats in 360° video coding, in which we exploit inactive regions. These regions are ignored in the reconstruction of the equirectangular format or the viewport in virtual reality applications. As the content of these pixels is irrelevant, we neglect the corresponding pixel values in rate-distortion optimization, residual transformation, as well as in-loop filtering and achieve bitrate savings of up to 10%.
