Mesh Compression Using Coding Units with Different Encoding Parameters - A simplified explanation of the abstract
This abstract first appeared for US patent application 18303411 titled 'Mesh Compression Using Coding Units with Different Encoding Parameters
Simplified Explanation
The patent application describes a system that compresses and encodes data for a three-dimensional mesh. The system includes an encoder that identifies sub-meshes and determines texture patches and geometry patches for each sub-mesh. The sub-meshes can be grouped into patches, patch-groups, and/or tiles. Different encoding parameters can be used for these coding units. However, the encoding parameters are adjusted for vertices that are shared between coding units to prevent the introduction of artifacts. A decoder is used to receive the encoded bit stream and reconstruct the original three-dimensional mesh.

Original Abstract Submitted
A system comprises an encoder configured to compress and encode data for a three-dimensional mesh. To compress the three-dimensional mesh, the encoder determines sub-meshes and for each sub-mesh: texture patches and geometry patches. Also, the sub-meshes may be grouped into patches, patch-groups, and/or tiles. Different encoding parameters may be used for such different coding units (e.g., patches, patch-groups and/or tiles). However, the encoding parameters are adjusted for vertices that are shared between coding units to avoid introduction of artefacts. A decoder receives a bit stream as generated by the encoder and reconstructs the three-dimensional mesh.
