Diff-Mosaic ：Augmenting Realistic Representations in Infrared Small Target Detection via Diffusion Prior(TGRS 2024) pdf

Framework

Experiment result

Inastall

conda create -n diffmosaic python=3.9
conda activate diffmosaic
pip install -r requirements.txt

pre-trained model

1. Download Open clip model( [huggingface]) and place it in ./weights/
2. Download Pixel-prior model ( NUDT-SIRST , SIRST) and place in ./weights/
3. Download Diff-prior model ( NUDT-SIRST, SIRST ) and place in ./weights/

Data Preparation

1. download the NUDT-SIRST dataset and SIRST dataset
2. run mosaic.py to generate Mosaic image
3. run degrade.py to get mix image

Generate augmentation sample

python inference.py --input ./add_noise/NUDT_mosaic/  --config configs/model/diff_prior.yaml --ckpt weights/NUDT_stage2/last.ckpt --swinir_ckpt weights/NUDT_stage1/last.ckpt --steps 50 --sr_scale 1 --repeat_times 1 --color_fix_type wavelet --output results/nudt_moc/ --device cuda --use_guidance --g_scale 400 --g_t_start 200

Detection network

1. Download dataset( [google]) and place it in ./detection_model/dataset/
2. Downolad pretrained model ( [google]) and place it in ./detection_model/pretrained_model/
3. cd ./detection_model/
