Semantic Segmentation Models/ Algorithms
- ResNet (Residual Network): Uses residual connections to enable training of very deep networks by allowing gradients to flow through layers without diminishing.
- HRNet (High-Resolution Network): Maintains high-res representations through the network, enabling it to capture fine details for accurate segmentation.
- FANet (Feature Agglomeration Network): Focuses on agglomerating features from different scales, enhancing the model's ability to discern finer details.
- DDRNet (Dual Dynamic Resolution Network): Employs dual-path architectures to balance efficiency and accuracy, facilitating real-time semantic segmentation.
Fuss Free Network (FFNET)
