The VPL-aware attention mechanism, while effective, may have limitations in handling certain challenging geometric variations in the road environment. To address these limitations and further improve its performance:
Adaptive Geometric Constraints: Enhance the attention mechanism to dynamically adjust the importance of vanishing points and lines based on the visibility and relevance of these geometric features in the input image. This adaptability can help in scenarios where traditional geometric assumptions may not hold.
Multi-Resolution Attention: Implement multi-resolution attention mechanisms that can focus on both local details and global context simultaneously. This can help in capturing intricate geometric variations in the road environment more effectively.
Contextual Memory Integration: Incorporate a contextual memory module that stores and retrieves relevant geometric information from previous frames or scenes to provide a more comprehensive understanding of the road environment and handle challenging variations.
Semantic Segmentation Fusion: Fuse the attention mechanism with semantic segmentation outputs to guide the model's focus on specific road elements, such as lane markings, road signs, or obstacles, in complex geometric scenarios.
Adversarial Training: Utilize adversarial training techniques to expose the attention mechanism to a wide range of challenging scenarios and geometric variations, enhancing its robustness and generalization capabilities.
