PEARL: Personalized Streaming Video Understanding Model

Paper | GitHub

PEARL-Bench is the first comprehensive benchmark designed specifically for Personalized Streaming Video Understanding (PSVU). It evaluates a model's ability to recognize user-defined concepts, localize them at precise timestamps, and answer personalized queries over continuous video streams.

The benchmark comprises 132 unique videos and 2,173 fine-grained annotations with precise timestamps. It supports two evaluation modes:

• Frame-level: Focuses on a specific person or object in discrete frames.
• Video-level: Focuses on personalized actions unfolding across continuous frames.

Dataset Structure

The dataset is organized as follows:

data/
  frame-level/
    annotations/   # Fine-grained annotations with timestamps
    output_clips/  # Generated scene clips
    videos/        # Source video files (.mp4)

Usage

For detailed instructions on downloading, merging, and extracting the data, as well as running the evaluation pipeline, please refer to the official GitHub repository.
