Video Trajectory Frame Extraction

via “video-trajectory-frame-extraction”

Dataset by nvidia. 3,34,635 downloads.

Unique: Implements lazy frame loading with configurable temporal sampling specifically for robot trajectory videos, avoiding full video decompression and enabling efficient streaming of 334K trajectories with variable sequence lengths

vs others: More memory-efficient than pre-extracting all frames to disk because it decodes on-demand during training, and more flexible than fixed-frame datasets because temporal sampling is configurable per trajectory
