OpenASL ROI Masks

ROI (region-of-interest) masks for the OpenASL dataset.

Contents

  • 94,994 .npz files, one per video clip.
  • Data is sharded into 10 tar archives (openasl_roi_masks_00.tar ... openasl_roi_masks_09.tar) for efficient download.

Each .npz file contains:

  • mask: uint8 array of shape (T, 224, 224) — per-frame binary mask.
  • fps: float64 scalar — frames per second.
  • height: int64 scalar — original frame height.
  • width: int64 scalar — original frame width.

Usage

import numpy as np
d = np.load("0005291-2021.1.6_warnock.npz")
mask = d["mask"]   # (T, 224, 224) uint8
fps = float(d["fps"])
h, w = int(d["height"]), int(d["width"])

Extraction

for f in openasl_roi_masks_*.tar; do tar -xf "$f"; done
