Abstract: Disclosed herein a device tracking gaze and method therefor. The device includes: an image acquisition unit configured to obtain an eyeball image; a pupil detection unit configured to detect a center of pupil by using the eyeball image; a virtual corneal reflection light position generator configured to process the eyeball image so that a virtual corneal reflection light is located at a predetermined point in the eyeball image; and a PCVR vector generator configured to generate a pupil center virtual reflection vector (PCVR vector) based on a position of the pupil center and a position of the virtual corneal reflection light.

Abstract: Disclosed herein is an immersive video processing method. The immersive video processing method includes: determining a priority order of pruning for input videos; extracting patches from the input videos based on the priority order of pruning; generating at least one atlas based on the extracted patches; and encoding metadata. Herein, the metadata may include information on a priority order of pruning among input videos.

Abstract: A video encoding method of encoding a multi-view image including one or more basic view images and a plurality of reference view images includes determining a pruning order of the plurality of reference view images, acquiring a plurality of residual reference view images, by pruning the plurality of reference view images based on the one or more basic view images according to the pruning order, encoding the one or more basic view images and the plurality of residual reference view images, and outputting a bitstream including encoding information of the one or more basic view images and the plurality of residual reference view images.

Abstract: An immersive video processing method according to the present invention includes: classifying view videos into a base video and an additional video; performing pruning for the view videos by referring to a result of the classification; generating an atlas based on a result of the pruning; determining a depth parameter of each view in the atlas; and encoding information indicating whether or not updating of the depth parameter is needed, based on whether or not the depth parameter of each view in the atlas is identical as in a previous atlas.
