MANUS-DexYCB: DexYCB-derived Multimodal Annotated Naturalistic Hand Understanding Dataset

MANUS-DexYCB is the DexYCB-derived subset of the Multimodal Annotated Naturalistic Hand Understanding (MANUS) dataset family. It is released as a source-specific repository because MANUS subsets are governed by different upstream licenses.

This repository contains only the DexYCB-derived MANUS test split. HaGRID/HaGRIDv2-derived data is released separately as MANUS-HaGRID.

Dataset Features in This Release

MANUS-DexYCB provides the following modalities where available:

  • full-scene RGB image;
  • full-scene depth map;
  • hand-region RGB crop;
  • hand-region depth map;
  • 2D bounding boxes for hand regions;
  • estimated MANO-style hand mesh annotations or related mesh metadata;
  • rendered mesh views from six canonical viewpoints: front, rear, left, right, top, and bottom;
  • primary and complementary mesh projection views where available;
  • companion text prompts describing image content, provided as the split-level prompt file listed below;
  • per-sample metadata recording source dataset, source id, split, available modalities, and license metadata.

Text prompts are provided in DexYCB_test_prompt.txt as a companion split-level file.

Configs and Splits

Config/Split Samples WebDataset shards Size
dexycb/test 7,836 7 5.58 GB

The canonical sample count is based on DexYCB_test_OG_image_paths.txt; other modalities are aligned to this OG image list.

Data Format

Data is stored as uncompressed WebDataset tar shards. Files belonging to the same sample share the same prefix:

dexycb_test_000001_processed_000001.json
dexycb_test_000001_processed_000001.full_rgb.png
dexycb_test_000001_processed_000001.full_depth.png
dexycb_test_000001_processed_000001.hand_rgb.png

dexycb_test_000001_processed_000001.vertices.json
dexycb_test_000001_processed_000001.mesh_front.png

The per-sample .json member records source and license metadata, source id, split, available modalities, and the number of files available for that sample. See docs/data_structure.md and docs/annotation_format.md for details.

Text Prompt Files

The following companion prompt file has been added at the repository root:

File Split Records/Lines Format Notes
DexYCB_test_prompt.txt dexycb/test 7,836 TXT One text prompt per line, aligned to the canonical DexYCB test OG image order.

Prompt files are optional companion annotations and are not packed into the WebDataset shards. Use this file when text conditioning or image-content descriptions are needed.

Metadata Files

  • metadata/dexycb_manifest.parquet
  • metadata/dexycb_manifest.csv
  • metadata/dexycb_manifest.jsonl
  • metadata/source_licenses.csv
  • metadata/release_schema.json
  • metadata/release_report.json
  • metadata/checksums.sha256
  • DexYCB_test_prompt.txt

The public manifest files do not contain local absolute source paths. They contain portable source and audit metadata, including sample id, source id, source license, available modalities, and shard path.
