Super-resolution of block-compressed texture for texture mapping applications

A system, comprising:

• circuitry configured to:
• receive a first texture block of a first block size;
• generate coded-texture values in a compressed domain based on application of a first block compression (BC) scheme on the received first texture block;
• apply a first machine learning model on the generated coded-texture values to generate super-resolution coded-texture values in the compressed domain;
• and
• process the generated super-resolution coded-texture values to generate a second texture block of a second block size, wherein the second block size is greater than the first block size, wherein the circuitry is further configured to process the generated super-resolution coded-texture values by:
• a conversion of the super-resolution coded-texture values in the compressed domain to a first compressed bit-stream,
• wherein
• the first compressed bit-stream comprises a set of second blocks of coded-bits, and
• each second block of coded-bits represents, in the compressed domain, a corresponding portion of the second texture block;
• and
• a decoding of the first compressed bit-stream to generate the second texture block of the second block size.

A non-transitory computer-readable medium having stored thereon, computer-executable instructions that when executed by a system, causes the system to execute operations, the operations comprising:

• receiving a first texture block of a first block size;
• generating coded-texture values in a compressed domain based on application of a first block compression (BC) scheme on the received first texture block;
• applying a first machine learning model on the generated coded-texture values to generate super-resolution coded-texture values in the compressed domain;
• and
• processing the generated super-resolution coded-texture values to generate a second texture block of a second block size, wherein the second block size is greater than the first block size, wherein the processing of the generated super-resolution coded-texture values comprises:
• converting the super-resolution coded-texture values in the compressed domain to a first compressed bit-stream,
• wherein
• the first compressed bit-stream comprises a set of second blocks of coded-bits, and
• each second block of coded-bits represents, in the compressed domain, a corresponding portion of the second texture block;
• and
• decoding the first compressed bit-stream to generate the second texture block of the second block size.
