Abstract
A new SEI message for the V-DMC standard is described herein, the zippering SEI. The zippering SEI message can be used by the decoder for the mesh reconstruction, where in the case of multiple sub-meshes, the zippering SEI provides ways to reduce common artifacts caused by independent sub-mesh encoding, such as holes and cracks on the mesh surface.
Claims21
A method programmed in a non-transitory memory of a device comprising:
- determining one or more border points in one or more sub-meshes;
- selecting a zippering implementation from a plurality of mesh zippering implementations;
- and
- merging each of the one or more border points with a corresponding point based on the selected mesh zippering implementation.
1 more element
An apparatus comprising:
- a non-transitory memory for storing an application, the application for:
- determining one or more border points in one or more sub-meshes;
- selecting a zippering implementation from a plurality of mesh zippering implementations;
- and
- merging each of the one or more border points with a corresponding point based on the selected mesh zippering implementation;
- and
- a processor coupled to the memory, the processor configured for processing the application.
