Abstract
A method, computer program, and computer system for point cloud coding is provided. Data corresponding to a point cloud is received, and one or more geometric features are detected from among the data corresponding to the point cloud. A representation is determined for one or more of the detected geometric features, and the received data is encoded or decoded based on the determined representations whereby the point cloud is reconstructed based on the decoded data.
Claims18
A method of point cloud coding, executable by a processor, comprising:
- detecting a geometric feature from among data corresponding to a point cloud;
- determining a representation for the geometric feature, wherein the detected geometric feature is specified as a start point and an end point;
- and
- decoding the data corresponding to the point cloud based on the determined representation, wherein the point cloud is reconstructed based on the decoded data.
A computer system for point cloud coding, the computer system comprising:
- one or more computer-readable non-transitory storage media configured to store computer program code;
- and
- one or more computer processors configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:
- detecting code configured to cause the one or more computer processors to detect a geometric feature from among data corresponding to a point cloud;
- determining code configured to cause the one or more computer processors to determine a representation for the detected geometric feature, wherein the detected geometric feature is specified as a start point and an end point;
- and
- decoding code configured to cause the one or more computer processors to decode the data corresponding to the point cloud based on the determined representation, wherein the point cloud is reconstructed based on the decoded data.
A non-transitory computer readable medium having stored thereon a computer program for point cloud coding, the computer program configured to cause one or more computer processors to:
- detect a geometric feature from among data corresponding to a point cloud;
- determine a representation for the detected geometric feature, wherein the detected geometric feature is specified as a start point and an end point;
- and
- decode the data corresponding to the point cloud based on the determined representation, wherein the point cloud is reconstructed based on the decoded data.
