Abstract
A novel method for signaling the packing method of 2D patches in canvas images, used in coding of 3D point clouds is described herein. The method utilizes a signal representation to indicate the orientation method to be used by the patches. Furthermore, an optimal method of coding the orientation information of each patch is described.
Claims12
A method programmed in a non-transitory memory of a device comprising:
- determining a patch orientation;
- and
- sending patch orientation information including when implementing adaptive packing sending a flag indicating a default orientation, and when implementing adaptive packing, utilizing an adaptive dictionary to indicate the patch orientation, wherein the adaptive dictionary is determined based on statistical analysis of patch orientation usage, and wherein the adaptive dictionary assigns a lowest code to a most used patch orientation.
An apparatus comprising:
- a non-transitory memory for storing an application, the application for:
- determining a patch orientation;
- and
- sending patch orientation information including when implementing adaptive packing sending a flag indicating a default orientation, and when implementing adaptive packing, utilizing an adaptive dictionary to indicate the patch orientation, wherein the adaptive dictionary is determined based on statistical analysis of patch orientation usage, and wherein the adaptive dictionary assigns a lowest code to a most used patch orientation;
- and
- a processor coupled to the memory, the processor configured for processing the application.
3 more elements
A system comprising:
- a determination module configured for determining a patch orientation;
- and
- an sending module configured for sending patch orientation information including when implementing adaptive packing sending a flag indicating a default orientation, and when implementing adaptive packing, utilizing an adaptive dictionary to indicate the patch orientation, wherein the adaptive dictionary is determined based on statistical analysis of patch orientation usage, and wherein the adaptive dictionary assigns a lowest code to a most used patch orientation.
