EventHO3D (Event-Augmented Add-On for HO3D-v2)

Event streams and XMem object masks that augment the HO3D-v2 evaluation split for Event6D (CVPR 2026).

Events are simulated from the original RGB frames (no real event camera). This dataset does NOT redistribute the HO3D images/depth — download those from the official source and merge with this release.

Sequences

13 video runs across 4 novel YCB objects: AP10–AP14 (pitcher), MPM10–MPM14 (potted meat can), SB11, SB13 (bleach), SM1 (mustard).

Layout (this release) 

EventHO3D/
├── evaluation_events/<seq>/   # simulated event streams (.npz per frame, ≈3 GB)
└── masks_XMem/<seq>/          # XMem object segmentation masks (≈80 MB)

Setup with original HO3D-v2

  1. Download HO3D-v2 evaluation from the official project page: https://www.tugraz.at/index.php?id=40231

  2. Place this release under the same parent so that evaluation/ (from HO3D-v2) and evaluation_events/ / masks_XMem/ (from here) sit side-by-side:

    EventHO3D/
├── evaluation/             # ← from official HO3D-v2 (rgb, depth, meta, hand_mask, ...)
├── evaluation_events/      # ← from this release
├── masks_XMem/             # ← from this release
└── ycb_models/             # ← YCB-Video models, see below

  3. YCB-Video models (ycb_models/{ob_name}/textured_simple.obj) are required by Ho3dReader.get_gt_mesh(). Download from https://rse-lab.cs.washington.edu/projects/posecnn/ (YCB_Video_Models.zip), or set YCB_MODELS_PATH=/path/to/ycb_models to a copy you already have.

Event file timing

Each evaluation_events/<seq>/XXXXXX.npz holds the events that occurred during the inter-frame interval ending at HO3D RGB frame XXXXXX (between rgb/(XXXXXX-1).jpg and rgb/XXXXXX.jpg, ≈ 1/30 s). Inside each .npz, key data is a structured array with fields (x, y, t, p) — event pixel coords, timestamp in seconds, polarity ±1.
