Contents
- 94,994
.npzfiles, 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:uint8array of shape(T, 224, 224)— per-frame binary mask.fps:float64scalar — frames per second.height:int64scalar — original frame height.width:int64scalar — 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
