Abstract
An encoding device and a method for point cloud encoding are disclosed. The method includes generating, for a 3D point cloud, an attribute frame and an occupancy map. The method also includes reducing a resolution of the frames over a number of sequential steps, until the frames are a predetermined size. After the frames are reduced to the predetermined size, the method includes increasing the resolution of the frames over the number of sequential steps while adding padding to modify at least some of the pixels in the attribute frame that do not represent points of the 3D point cloud. While the resolution of the attribute frame is incrementally increased, the method includes performing smoothing on the pixels in the attribute frame that do not represent the points of the 3D point cloud. The method additionally includes encoding the frames to generate a bitstream and then transmitting the bitstream.
