RGB Frames 🖼️

This directory contains extracted RGB frames from assembly videos. Frames are organized by furniture category, furniture name, and video ID:

rgb-frames/<category>/<furniture_name>/<video_id>/<frame_file>.jpg

Example:

rgb-frames/Bench/applaro/KPs0ik2FcsY/0.jpg
rgb-frames/Bench/applaro/KPs0ik2FcsY/frame_id_to_fn.json

Frame Files

• JPEG filenames are local sequential frame filenames, such as 0.jpg, 1.jpg, and 2.jpg.
• The original source-video frame IDs may be different from the local JPEG filenames.

frame_id_to_fn.json Schema

Each video folder contains a frame_id_to_fn.json file mapping source video frame IDs to local extracted image filenames.

Example shape:

{
  "1161": "0.jpg",
  "1191": "1.jpg",
  "1221": "2.jpg"
}

Key	Value	Description
source frame ID	string	Frame index in the original or processed source video.
local filename	string	JPEG filename in the same directory.

Use this mapping when aligning question prompt frames, extracted images, masks, and source video timestamps.
