Abstract
At least one embodiment relates to a method for adding at least one 3D sample to a point cloud frame and for assigning a color-coding mode to said at least one 3D sample, said color-coding mode indicating if color information associated with said at least one 3D sample is explicitly encoded in a bitstream or if said color information is implicit.
Claims19
A method comprising:
- adding at least one 3D sample to a point cloud frame, said at least one 3D sample being added according to a difference between a depth value of at least one neighboring 3D sample of a current 3D sample of the point cloud frame and a depth value of said current 3D sample, wherein the difference between the depth value of the neighboring 3D sample and the depth value of said current 3D sample is a first depth difference determined as a maximum depth difference between depth values of neighboring 3D samples of the current 3D sample and the depth value of the current 3D sample, and wherein at least one 3D sample is added with a depth value belonging to a range from the depth value of the current 3D sample of said point cloud frame and a depth value being equal to the sum of the depth value of said current 3D sample and the first depth difference minus 1.
A device comprising at least one processor configured to:
- add at least one 3D sample to a point cloud frame, said at least one 3D sample being added according to a difference between a depth value of at least one neighboring 3D sample of a current 3D sample and the depth value of said current 3D sample, wherein the difference between the depth value of the neighboring 3D sample and the depth value of said current 3D sample is a first depth difference determined as a maximum depth difference between depth values of neighboring 3D samples of the current 3D sample and the depth value of the current 3D sample, and wherein at least one 3D sample is added with a depth value belonging to a range from the depth value of the current 3D sample of said point cloud frame and a depth value being equal to the sum of the depth value of said current 3D sample and the first depth difference minus 1.
