ABC: Attention with Bilinear Correlation for Infrared Small Target Detection

We have open sourced a framework for infrared small target segmentation, which can easily add and modify models, train and test, etc. Welcome to use: https://github.com/PANPEIWEN/Infrared-Small-Target-Segmentation-Framework

Infrared small target detection (ISTD) has a wide range of applications in early warning, rescue, and guidance. However, CNN based deep learning methods are not effective at segmenting infrared small target (IRST) that it lack of clear contour and texture features, and transformer based methods also struggle to achieve significant results due to the absence of convolution induction bias. To address these issues, we propose a new model called attention with bilinear correlation (ABC), which is based on the transformer architecture and includes a convolution linear fusion transformer (CLFT) module with a novel attention mechanism for feature extraction and fusion, which effectively enhances target features and suppresses noise. Additionally, our model includes a u-shaped convolution-dilated convolution (UCDC) module located deeper layers of the network, which takes advantage of the smaller resolution of deeper features to obtain finer semantic information. Experimental results on public datasets demonstrate that our approach achieves state-of-the-art performance.

Training

Single GPU Training

python train.py <CONFIG_FILE>

For example:

python train.py configs/abcnet/abcnet_clft-l_512x512_1500e.py

Multi GPU Training

nproc_per_node is the number of gpus you are using.

python -m torch.distributed.launch --nproc_per_node=[GPU_NUMS] train.py <CONFIG_FILE>

For example:

python -m torch.distributed.launch --nproc_per_node=4 train.py configs/abcnet/abcnet_clft-l_512x512_1500e.py

Notes

• Be sure to set args.local_rank to 0 if using Multi-GPU training.

Test

python test.py <CONFIG_FILE> <SEG_CHECKPOINT_FILE>

For example:

python test.py configs/abcnet/abcnet_clft-l_512x512_1500e.py work_dirs/abcnet_clft-l_512x512_1500e/20221009_231431/best.pth.tar

If you want to visualize the result, you only add --show at the end of the above command.

The default image save path is under <SEG_CHECKPOINT_FILE>. You can use --work-dir to specify the test log path, and the image save path is under this path by default. Of course, you can also use --show-dir to specify the image save path.
