Abstract: Embodiments of the present disclosure provide a solution for point cloud coding. A method for point cloud coding is proposed. The method comprises: determining, during a conversion between a current frame of a point cloud sequence and a bitstream of the point cloud sequence, at least one neighbor list comprising a set of neighbor points of a current point of the current frame based on geometry information of the set of neighbor points; and performing the conversion based on the at least one neighbor list. Compared with the conventional solution, the proposed method can advantageously improve the point cloud coding efficiency and coding quality.

Abstract: The disclosure provides a method, apparatus, electronic device and storage medium for permission synchronization. In the method, a set of first permission information to be synchronized from a second operating system running on a first operating system environment is obtained. The set of first permission information to be synchronized is transmitted to a shared memory area of the first operating system and the set of first permission information to be synchronized is stored in the shared memory area of the first operating system. Permission information is read from the shared memory area by the first operating system.
