Requirements

• pytorch=0.4.1
• python=3.x
• torchvision
• numpy
• opencv-python
• jupyter notebook (optional)
• anaconda (suggeted)

Configuration

# Create your virtual environment using anaconda
conda create -n IFCNN python=3.5

# Activate your virtual environment
conda activate IFCNN

# Install the required libraries
conda install pytorch=0.4.1 cuda80 -c pytorch
conda install torchvision numpy jupyter notebook
pip install opencv-python

Usage

# Clone our code
git clone https://github.com/uzeful/IFCNN.git
cd IFCNN/Code

# Remember to activate your virtual enviroment before running our code
conda activate IFCNN

# Replicate our image method on fusing multiple types of images
python IFCNN_Main.py

# Or run code part by part in notebook
jupyter notebook IFCNN_Notebook.ipynb

Typos

1. Eq. (4) in our paper is wrongly written, the correct expression can be referred to the official expression in OpenCV document, i.e., , where , , , and is the scale factor chosen for achieving .
2. Stride and padding parameters of CONV4 are respectively 1 and 0, rather than both 0.

Highlights

• Propose a general image fusion framework based on convolutional neural network
• Demonstrate good generalization ability for fusing various types of images
• Perform comparably or even better than other algorithms on four image datasets
• Create a large-scale and diverse multi-focus image dataset for training CNN models
• Incorporate perceptual loss to boost the model’s performance
