SiameseFC PyTorch Implementation: A Step-by-Step Guide

Introduction

Welcome to your practical guide for implementing the SiameseFC object tracker using PyTorch. This article will walk you through the project inspired by the original research presented in the paper Fully-Convolutional Siamese Networks for Object Tracking, with additional insights from their original Matlab implementation available here and the adapted TensorFlow version here.

Project Organization

This project is meticulously organized into three main parts:

• Training
• Tracking
• Visualization Application

Training

The objective of the training is to calibrate the Siamese Network to learn a similarity metric between image patches. Think of it as teaching a friend to recognize faces by showing them pairs of images: one of a known face and another of someone else. Your friend evaluates how similar the two faces are!

As described in the project, the Training part implements the following:

python train.py --data_dir FULL_PATH_TO_DATASET_ROOT --exp_name EXP_NAME

This command sets up the training process, akin to setting up a cooking recipe where you determine your ingredients (data location) and the dish you want to create (experiment name).

How to Run – Training

Here’s a step-by-step guide to assist you:

1. Prerequisites: Ensure you have the following setup:
• Python 3.6
• PyTorch 4.1
• CUDA-enabled GPU (GTX 1080 Ti or GTX 950M recommended)

Install dependencies using the following commands:

pip install scipy scikit-learn tqdm tensorboardx imageio pyqt5 pyqtgraph

2. Download the ImageNet VID Dataset: Get it from this link. Store it on your SSD for optimal performance.
3. Create an Experiment Folder: Navigate to:

cd training/experiments
mkdir EXP_NAME
cp default/parameters.json EXP_NAME

4. Edit Parameters: Modify the parameters.json file with your preferences, referring to the parameter descriptions within the project.
5. Executing Training: Use:

python train.py --data_dir FULL_PATH_TO_DATASET_ROOT --exp_name EXP_NAME

Troubleshooting

If you encounter issues, here are some troubleshooting tips:

• Python Compatibility: Make sure you are using Python 3.6 as some libraries may not support newer versions.
• Environment Setup: Ensure PyTorch and the other dependencies are correctly installed. Run the installation commands again if in doubt.
• Dataset Accessibility: Verify that the path to the ImageNet dataset is correct and the dataset is fully extracted.

Tracking

Although tracking is still under development, it builds on the trained model and is designed to follow the detected objects through frames, similar to how a detective follows a suspect through a busy street, keenly observing their movements despite distractions.

Visualization Application

This is a tool developed to visually assess the network’s output in real-time. It provides insight into how well the Siamese network can compare and identify the similarity of objects in video frames, much like an artist observing different colors on a palette before applying them to a canvas.

Conclusion

Integrating the SiameseFC tracker into your projects opens up various possibilities in object detection and tracking. Remember, continuing research and experimentation is the key to mastering such complex systems.
