Nested U-Net architecture is pretty cool, and it has better performance compared to U-Net.
- UNet++ aims to improve segmentation accuracy, with a series of nested, dense skip pathways.
- Redesigned skip pathways made optimisation easier with the semantically similar feature maps.
- Dense skip connections improve segmentation accuracy and improve gradient flow.
- Deep supervision allows for model complexity tuning to balance between speed and performance optimisation.
