[ECCV'22 Oral] Towards Grand Unification of Object Tracking

Unicorn 🦄 : Towards Grand Unification of Object Tracking

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.
