DCFNET: DISCRIMINANT CORRELATION FILTERS NETWORK FOR VISUAL TRACKING_(arXiv)

By Qiang Wang, Jin Gao, Junliang Xing, Mengdan Zhang, Weiming Hu

Introduction

Discriminant Correlation Filters (DCF) based methods now become a kind of dominant approach to online object tracking. The features used in these methods, however, are either based on hand-crafted features like HoGs, or convolutional features trained independently from other tasks like image classification. In this work, we present an end-to-end lightweight network architecture, namely DCFNet, to learn the convolutional features and perform the correlation tracking process simultaneously.

Requirements

git clone --depth=1 https://github.com/foolwood/DCFNet.git

Requirements for MatConvNet 1.0-beta24 (see: MatConvNet)

1. Downloading MatConvNet

cd <DCFNet>
git clone https://github.com/vlfeat/matconvnet.git

2. Compiling MatConvNet

Run the following command from the MATLAB command window:

cd matconvnet
run matlab/vl_compilenn

[Optional]

If you want to reproduce the speed in our paper, please follow the website to compile the GPU version.

Tracking

The file demo/demoDCFNet.m is used to test our algorithm.

To reproduce the performance on OTB , you can simple copy DCFNet/ into OTB toolkit.

[Note] Configure MatConvNet path in tracking_env.m

Training

1.Download the training data. (VID)

2.Data Preprocessing in MATLAB.

cd training/dataPreprocessing
data_preprocessing();
analyze_data();

3.Train a DCFNet model.

train_DCFNet();

Results

DCFNet obtains a significant improvements by

• Good Training dataset. (TC128+UAV123+NUS_PRO -> VID)
• Good learning policy. (constant 1e-5 -> logspace(-2,-5,50))
• Large padding size. (1.5 -> 2.0)

The OPE/TRE/SRE results on OTB BaiduYun or GoogleDrive.
