World-Snapshot/WorldSnapshot-Horizon

WorldSnapshot Horizon

WorldSnapshot Horizon is a compact, self-contained release of the visual inputs and WSG-derived annotations used for the external comparisons in the WSM paper. It contains two deliberately separate collections:

• avis-heldout reproduces the held-out AVIS examples used in the paper. These examples were not used to train WSM. They are duplicated here so that the released comparison suite does not depend on private filesystem paths or a second dataset download.
• post-release-2026 contains frames from Wikimedia Commons videos captured or published between 2026-08-02 and 2026-09-04. They were not used in WSM training and were selected by date to reduce overlap with the pretraining data of large foundation models.

The release covers five mappings from the paper: RGB to relative depth, edge plus reference RGB to RGB, normal to edge, relative depth to normal, and edge to human-part segmentation. It contains inputs, references, targets, validity masks, task manifests, provenance, and modality-scoped WSG arrays. Model predictions are intentionally excluded.

Contents

Collection	RGB to depth	Edge + reference to RGB	Normal to edge	Relative depth to normal	Edge to human parsing
AVIS held-out	23	24	24	24	24
Post-release 2026	24	24	24	24	24

Repeated task records may refer to the same source frame. Shared AVIS source arrays are stored once under data/avis-heldout/source-wsg.

Each manifest is the authoritative index. Its path fields are relative to the repository root. AVIS source NPZ files contain:

• wsg_data: H x W x C float16 values copied from the encoded WSV frame;
• channels: the corresponding WSG channel indices;
• frame_key: the original frame key.

Post-release wsg_condition files are already modality-scoped NPZ inputs made by the same WSG annotation pipeline. The manifest records the channels and the task-specific crop or normalization contract where applicable.

Provenance and licenses

Every post-release source retains its Wikimedia Commons page, author, capture date, upload timestamp, and item-level license in the provenance manifest. Those media remain under their individual source licenses and attribution requirements. AVIS material follows the terms of its originating release. WSG-derived annotations and arrays are provided for research and reproducibility; this repository does not apply one blanket license to all underlying media.

Reproducibility

The task manifests preserve the exact samples and modality routes used by the paper comparison. File integrity can be checked with:
