New OptiModNet model achieves state-of-the-art optic disc segmentation with high efficiency

Researchers have developed OptiModNet, a novel hybrid deep learning architecture designed for efficient and accurate segmentation of the optic disc and cup. This model combines U-Net and Transformer elements, incorporating grouped-query and channel attention mechanisms to improve both local and global feature representation. OptiModNet also utilizes an Aggregated Pyramid Loss to enhance gradient flow and structural consistency. Evaluated on the REFUGE2 dataset, the model achieved state-of-the-art performance, surpassing existing methods by over 2.5% while maintaining a low computational footprint of 3.73 GFLOPs and 1.93M parameters, making it suitable for large-scale screening in resource-limited clinical settings.
