Unicorn 🦄 : Towards Grand Unification of Object Tracking

PWC PWC PWC PWC PWC PWC Models on Hugging Face Unicorn

This repository is the project page for the paper Towards Grand Unification of Object Tracking

Highlight

  • Unicorn is accepted to ECCV 2022 as an oral presentation!
  • Unicorn first demonstrates grand unification for four object-tracking tasks.
  • Unicorn achieves strong performance in eight tracking benchmarks.

Introduction

  • The object tracking field mainly consists of four sub-tasks: Single Object Tracking (SOT), Multiple Object Tracking (MOT), Video Object Segmentation (VOS), and Multi-Object Tracking and Segmentation (MOTS). Most previous approaches are developed for only one of or part of the sub-tasks.

  • For the first time, Unicorn accomplishes the great unification of the network architecture and the learning paradigm for four tracking tasks. Besides, Unicorn puts forwards new state-of-the-art performance on many challenging tracking benchmarks using the same model parameters.

This repository supports the following tasks:

Image-level

  • Object Detection
  • Instance Segmentation

Video-level

  • Single Object Tracking (SOT)
  • Multiple Object Tracking (MOT)
  • Video Object Segmentation (VOS)
  • Multi-Object Tracking and Segmentation (MOTS)

Demo

Unicorn conquers four tracking tasks (SOT, MOT, VOS, MOTS) using the same network with the same parameters.
