Learning Object-aware Anchor-free Networks for Real-time Object Tracking

• Code and models for double blind review in ECCV2020.

Introduction

Anchor-based Siamese trackers have witnessed tremendous success in visual tracking, yet their robustness still leaves a gap with recent state-of-the-art approaches. We find the underlying reason is that the regression network in anchor-based methods is only trained on the positive anchor boxes. This mechanism makes it difficult to refine the anchors whose overlap with the target objects are small.

Our proposals mitigate the problem by,

1. We propose a novel anchor-free algorithm for realtime visual tracking. It is capable of rectifying the imprecise bounding-box predictions whose overlap with the target objects are small.

2. We introduce an adaptive feature alignment mechanism to set up a correspondence between the objectaware features and the predicted bounding boxes. This leads to a more robust classification of foreground objects and background clutters.

Quick Start

Installation

bash install.sh ocean
