Abstract: An encoding device and a method for point cloud encoding are disclosed. The method for encoding includes segmenting an area including points representing a three-dimensional (3D) point cloud into multiple voxels. The method also includes identifying a normal score for each of the points of the 3D point cloud and a smoothing score for each of the multiple voxels that include at least one of the points of the 3D point cloud. The method further includes grouping each point of the 3D point cloud to one of multiple projection planes based on the normal score and the smoothing score to generate refined patches that represent the 3D point cloud. Additionally, the method includes generating frames that include pixels that represent the refined patches. The method also includes encoding the frames to generate a bitstream and transmitting the bitstream.

Abstract: An encoding device and methods for point cloud encoding are disclosed. The method for encoding includes generating, using a processor of an encoder, a first frame and a second frame that include patches representing a cluster of points of three-dimensional (3D) point cloud; identifying a patch to segment in the patches of the first frame and the second frame; determining, in response to identifying the patch, a path representing a boundary between segmented regions within the patch; segmenting the patch along the path into two patches for the first frame and the second frame; encoding the first frame and the second frame to generate a compressed bitstream; and transmitting, using a communication interface operably coupled to the processor, the compressed bitstream.

Abstract: A decoding device, an encoding device and a method for point cloud decoding is disclosed. The method includes receiving a compressed bitstream. The method also includes decoding the compressed bitstream into 2-D frames that represent a 3-D point cloud. Each of the 2-D frames including a set of patches, and each patch includes a cluster of points of the 3-D point cloud. The cluster of points corresponds to an attribute associated with the 3-D point cloud. One patch of the set of patches, the set of patches, and the 2-D frames correspond to respective access levels representing the 3-D point cloud. The method also includes identifying a first and a second flag. In response to identifying the first and the second flag, the method includes reading the metadata from the bitstream. The method further includes generating, based on metadata and using the sets of 2-D frames, the 3-D point cloud.

Abstract: A decoding device, an encoding device and a method for point cloud decoding is disclosed. The method includes decoding the compressed bitstream into a first set and second set of 2-D frames. The first set of 2-D frames include first set of regular patches representing geometry of a 3-D point cloud and the second set of 2-D frames include first set of regular patches representing texture of the 3-D point cloud. The method includes identifying in the first set of 2-D frames, a missed points patch representing geometry of points of the 3-D point cloud not included in the regular patches, and in the second set of 2-D frames a missed points patch that represents texture of the points of the 3-D point cloud not included in the regular patches. The method also includes generating, using the set of 2-D frames, the 3-D point cloud using the missed points patches.

Abstract: A method for real-time multi-frame super resolution (SR) of video content is provided. The method includes receiving a bitstream including an encoded video, motion metadata for a plurality of blocks of a frame of video content, and parameters. The motion metadata is estimated from the original video before downsampling and encoding. The motion metadata is averaged over consecutive blocks. The method includes upscaling the motion metadata for the plurality of blocks. The method also includes upscaling the decoded video using the upscaled motion metadata. The method also includes deblurring and denoising the upscaled video.

Abstract: An encoding device, a decoding device, and a method for mesh decoding are disclosed. The method for mesh decoding includes receiving a bitstream. The method also includes decoding a frame that includes pixels from the bitstream. A portion of the pixels of the frame represent geometric locations of vertices of a 3D mesh that are organized into overlapped patches. The method further includes decoding connectivity information from the bitstream. Additionally, the method includes identifying triangles associated with the overlapped patches. The triangles represented in an overlapped patch of the overlapped patches are allocated to a projection direction based on a normal vector associated with each of the triangles of the overlapped patch. The method also includes reconstructing the 3D mesh based on the connectivity information and the overlapped patches.
