j2k-ml

Thin Burn 0.21 adapter for the j2k owned batch codec.

j2k-ml is an independent integration maintained by the j2k project. It is not an official Tracel or Burn crate. It is included in the j2k 0.7.5 release and follows the workspace's reviewed semver policy.

The codec crates own parsing, preparation, grouping, decoding, and device execution. This crate only allocates ordinary rank-4 Burn integer tensors and connects their storage to persistent CPU, CUDA, or Metal codec sessions. It does not own normalization, augmentation, dataset policy, or another decoding pipeline.

See the single Burn integration guide for the API, support matrix, safety boundary, validation commands, and benchmark status. The published API is on docs.rs, source is maintained in the J2K repository, and the codec support boundary is recorded in docs/public-support.md.
