Abstract
A device includes a processor that is configured to obtain first facets of a first wide field-of-view image. An object is identified in a facet of the first facets. A second wide field-of-view image is obtained. A location of the object is identified in the second wide field-of-view image. Using the location of the object, the second wide field-of-view image is partitioned into second facets such that no boundary of any of the second facets overlaps the object. The second facets are then encoded in a compressed bitstream.
Claims20
A device, comprising:
- a processor configured to:
- obtain first facets of a first wide field-of-view image;
- identify an object in a facet of the first facets;
- obtain a second wide field-of-view image;
- identify a location of the object in the second wide field-of-view image;
- partition, using the location of the object, the second wide field-of-view image into second facets such that no boundary of any of the second facets overlaps the object;
- and
- encode the second facets in a compressed bitstream.
A method for reducing decoding artefacts, comprising:
- performing a first cube projection operation on a first wide field-of-view image to obtain first facets;
- identifying an object in one of the first facets;
- performing a second cube projection operation on a second wide field-of-view image to obtain second facets,
- wherein the second cube projection operation is such that no boundary of any of the second facets overlaps the object, and
- wherein the second wide field-of-view image is obtained at a different time from the first wide field-of-view image;
- and
- encoding at least one of the second facets using at least one of the first facets.
A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations to reduce decoding artefacts, the operations comprising to:
- obtain a first image and a second image, wherein the first image and the second image are images of a wide field-of-view image;
- use parallax information obtained using an overlap region between the first image and the second image to detect relative distances of a first object and a second object in at least one of the first image or the second image from one or more imaging devices used to obtain the first image and the second image, wherein the first object is detected to be farther away than the second object;
- partition the wide field-of-view image into facets based on the relative distances such that no boundary of any of the facets overlaps the second object;
- and
- encode the facets of the wide field-of-view image.
