An decoding device, an encoding device and a method for point cloud encoding is disclosed. The method includes generating, from a three-dimensional point cloud, multiple two-dimensional frames, the two-dimensional frames including at least a first frame representing a geometry of points in the three-dimensional point cloud and a second frame representing texture of points in the three-dimensional point cloud. The method also includes generating an occupancy map indicating locations of pixels in the two-dimensional frames that represent points in the three-dimensional point cloud. The method further includes encoding the two-dimensional frames and the occupancy map to generate a compressed bitstream. The method also includes transmitting the compressed bitstream.

Point cloud and mesh compression using image/video codecs

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 2D frames that represent a 3D point cloud, each of the 2D frames including a set of patches representing a cluster of pixels of the 3D point cloud. The method further includes identifying an occupancy map included in the compressed bitstream. The method additionally includes identifying valid boundary points located at a boundary of a patch of the set of patches based on the occupancy map and identifying valid neighboring points of each of the valid boundary points of the patch. The method also includes generating the 3D point cloud using the 2D frames based on the valid neighboring points and the valid boundary points.

Visual quality enhancement of reconstructed point clouds via color smoothing

An electronic device configured to render a three hundred and sixty (360) degree image includes a communication unit and a processor. The communication unit is configured to receive a first image, a second image, and metadata from a camera. The processor is configured to render the 360 degree image by transforming the first image and the second image to compensate for a light fall-off, unwarping the transformed first image and second image, aligning the unwarped first image and second image, and blending the aligned unwarped first image and second image.
