DAVIS Dataset Explorer

Interactive browser for the DAVIS 2017 Video Object Segmentation benchmark (480p split).

Features

Tab	What it does
📋 Browse	Filter & search all 90 sequences; click a row to inspect metadata
🔍 Viewer	Frame-by-frame scrubber with DAVIS palette mask overlay; single-sequence video playback
🖼 Gallery	Thumbnail grid of all sequences; click a thumbnail to instantly play it
📺 Multi-Video	Paged 3×3 video grid — page through all 90 sequences, 9 at a time
⚖️ Compare	Up to 6 sequences side-by-side
📊 Statistics	Distribution plots (frames, objects, splits, resolution)

First-run behaviour

On the first startup the app downloads DAVIS-2017-trainval-480p.zip (~800 MB) from the official ETH Zurich server and extracts it to DAVIS_ROOT.

With HF Spaces persistent storage the data is stored under /data/DAVIS and the MP4 cache under /data/DAVIS_explorer_cache — both survive restarts.

Environment variables

Variable	Default	Description
DAVIS_ROOT	/data/DAVIS (Spaces) or local path	Dataset root directory
DAVIS_CACHE_DIR	DAVIS_ROOT/../DAVIS_explorer_cache	Where encoded MP4s are stored
