LFA: Layer Feature Attention for Run-Time Introspection of 2D Object Detectors in Automated Driving
Researchers have developed a new method called Layer Feature Attention (LFA) to improve the introspection of 2D object detectors used in automated driving systems. LFA utilizes an attention mechanism to aggregate features from multiple layers of the detector's backbone, unlike previous methods that relied on only the last layer or handcrafted statistics. This approach allows for more accurate prediction of detector errors by considering different levels of visual abstraction, from fine-grained details in low-level layers to semantic information in high-level layers. Experiments on the KITTI and BDD100K datasets show that LFA outperforms existing methods in predicting detector failures. AI
