DSNet：A Novel Way to Use Atrous Convolutions in Semantic Segmentation

🚀 If it helps you, click a star! ⭐

a novel real-time model in semantic segmentation. Paper: ([PDF]https://arxiv.org/abs/2406.03702)) PWC PWC PWC

This is the implementation for DSNet. DSNetV2 is currently under development... DSNetV2 will offer a better balance between speed and accuracy, as well as a more comprehensive DSNet family ranging from small to large models.

News 2024/7/28

We extended the MSAF and MSA experiments for classification by applying them to models like ResNet18. On the ImageNet1K task, this led to a 3.3% accuracy improvement with only a 1% increase in computational cost! We will include a more detailed explanation of this module in our paper for submission to a high-quality journal.

Environment:

PyTorch 1.10

python 3.8

4*RTX4090 or 8*RTX4090

pip install -r requirements.txt

Highlight

Params vs mIOU on Cityscapes val set ADE20K

• We revisited the design of atrous convolutions in CNNs,and explored three empirical guidelines for atrous convolution. Based on the above guidelines, we proposed a novel Dual-branch network.

• DSNet achieves a new state-of-the-art trade-off between accuracy and speed on ADE20K, Cityscapes,and BDD10K.

Train and Inference speed:

This implementation is based on HRNet-Semantic-Segmentation and PIDNet. Please refer to their repository for installation and dataset preparation. The inference speed is tested on single RTX 3090 or RTX4090. BDD10K has not been implemented in the above link. The dataset storage format is as follows. Download link: web page
