Mirk

Mirk is a library and a pipeline that combines classical Computer Vision (CV) models with Large Visual Models (LVMs) to provide detailed analysis and understanding of a video. The classical CV model handles initial processing and object detection, while the LVM generates rich, contextual interpretations of the visual content.

Overview

Mirk works by:

  1. Taking an input video
  2. Using a CV model to detect objects of interest. Objects (classes) of interest are specified by the user
  3. When a specified object is identified, triggering a VLM to generate detailed explanations about what is seen in the video, to reason about the detected object and its context based on the provided question

Installation

pip install mirk

Quick Start

Check out the example to see how to use Mirk.

For your convenience, we provide a bash script that downloads a sample video and runs the one-shot example:

cd examples
./one_shot.sh

with the following output:

Question: What are the people doing in the image?
Answer: The people in the image are playing with basketballs, passing them to each other. There is a group of individuals, and some are walking while others are engaged in the activity. It's a scene from a well-known experiment involving selective attention.
