Note

We have updated the existing bugs in the original code. Please download the current project and weights again for testing and training.【07/10】

Data preparation

1. Download the COCO dataset to .\datasets\COCO\ (path2COCO)
2. Download the IVS dataset to .\datasets\IVS\ (path2IVS)
3. Download the label of IVS dataset to .\datasets\IVS_Label\ (path2IVS_Label)
4. Generate pseudo-infrared images for each image in the COCO dataset using CPSTN and store the results in .\datasets\COCO_CPSTN\ (path2COCO_CPSTN)
5. Generate pseudo-infrared images for each image in the IVS dataset using CPSTN and store the results in .\datasets\IVS_CPSTN\ ((path2IVS_CPSTN))

Installation

The code is implemented in python=3.6, as well as pytorch=1.9 and opencv-python=4.6.0.66. Please follow the instructions here to install both PyTorch dependencies. Installing PyTorch with CUDA support is strongly recommended.

Training

1. Train stage1: Registration and semantic feature extraction. cd train_stage1 and configuring dataset paths, then run python train_stage1.py

2. Train stage2: Training CSC and SSR modules. cd train_stage2 and configuring dataset paths, then run python train_stage2.py

3. Train stage3: Training fusion module. cd train_stage3 and configuring dataset paths, then run python train_stage3.py

Test

Download pre-trained models on Google Drive or Baidu Yun and configure the path reg_weight_path, fusion_weight_path. We provide two matching modes, one is semantic object-oriented matching, setting matchmode = "semantic", and the other is global image oriented matching, setting matchmode = "scene".

On a dataset

Configuring dataset paths, then run python test.py

On a pair of images

Configuring images path, then run python inference_one_pair_images.py
