  • Publication number: 20240169596
    Abstract: An encoding method, a decoding method, and a device for point cloud compression are provided. The encoding method includes the following. Point cloud data corresponding to a first frame is obtained, and is distinguished into a global point cloud set and at least one object point cloud set according to a reference frame. The object point cloud set corresponds to at least one reference object point cloud set. A global dynamic model corresponding to the global point cloud set is calculated and an object dynamic model corresponding to the object point cloud set is calculated. A bitstream is generated. The bitstream includes the global point cloud set, the global dynamic model corresponding to the global point cloud set, a serial number of each object point in the reference object point cloud set, and the object dynamic model corresponding to the object point cloud set.

  • Publication number: 20230113529
    Abstract: An encoding method and an electronic device for point cloud compression are provided. A two-dimensional image and an occupancy map of a point cloud are obtained. An occupancy status of point cloud data of each pixel sample in the two-dimensional image is determined according to the occupancy map. A weight parameter of each pixel sample in an encoding block of the two-dimensional image is determined according to the occupancy statuses of point cloud data of multiple pixel samples. Multiple rate-distortion costs respectively corresponding to multiple encoding operation options are calculated according to the weight parameter of each pixel sample in the encoding block. One of the encoding operation options is determined to be used to perform an encoding operation on the encoding block according to a minimum rate-distortion cost among the rate-distortion costs.

  • Publication number: 20230005189
    Abstract: A content patch encoding method and a content patch decoding method are provided. The content patch decoding method includes: receiving a bit stream, and obtaining multiple information corresponding to a point cloud patch and a mesh patch accordingly; obtaining a connectivity between multiple vertices of the mesh patch based on the bit stream; and reconstructing the point cloud patch and the mesh patch based on the information and the connectivity between the vertices.
