Abstract

The content discusses the importance of reliable object detection in automated driving systems and introduces a novel introspection solution to monitor errors. It compares various introspection mechanisms, evaluates their performance on different datasets, and analyzes computational requirements. The core focus is on enhancing error detection in 2D object detection systems through introspection mechanisms. The study highlights the significance of accurate perception for safe operation of automated driving systems and proposes a comprehensive evaluation framework for comparing different introspection methods. Key points include the need for robust perception systems in ADS, the introduction of an innovative introspection solution using neural activation patterns, comparative analysis of state-of-the-art methods, evaluation on KITTI and BDD datasets, and considerations for computational efficiency. The proposed method shows superior performance in reducing missed error ratios compared to existing techniques. It addresses the critical need for resilient perception systems in ADS through effective error monitoring and detection mechanisms.

Stats

An absolute reduction in the missed error ratio of 9% to 17% was achieved in the BDD dataset. The proposed mechanism requires less combined time for pre-processing and inference than other methods. HIMF is the fastest and least memory-intensive representation. SF simplifies neural network activation using statistical functions. CLF and LF-ASH contain more information for error detection, resulting in longer inference times and higher memory requirements.
