OptiModNet: A UNet-Transformer Hybrid with Grouped-Query and Channel Attention for Optic Disc and Cup Segmentation
TL;DR
OptiModNet is a novel hybrid architecture combining UNet and Vision Transformer elements for efficient optic disc and cup segmentation. It achieves state-of-the-art performance with only 3.73 GFLOPs and 1.93M parameters, surpassing existing methods by over 2.5%.
✦ Why It Matters
Implement OptiModNet for efficient and accurate glaucoma screening in clinical settings today.
Key Takeaways
- Utilize OptiModNet for efficient glaucoma detection.
- Leverage grouped-query and channel attention for better segmentation.
- Implement Aggregated Pyramid Loss for improved model training.
- Evaluate performance on REFUGE2 dataset for validation.
How It Works
OptiModNet combines UNet's ability to capture local features with Vision Transformers' strength in modeling global context. It uses grouped-query attention to focus on relevant features while channel attention enhances the representation of important channels.
The model's architecture allows for efficient processing, making it suitable for real-time applications.
