SPG: Sparse-Projected Guides with Sparse Autoencoders for Zero-Shot Anomaly Detection
Tomoyasu Nanaumi, Yukino Tsuzuki, Junichi Okubo +2
We study zero-shot anomaly detection and segmentation using frozen foundation model features, where all learnable parameters are trained only on a labeled auxiliary dataset and dep…
OD-RASE: Ontology-Driven Risk Assessment and Safety Enhancement for Autonomous Driving
Kota Shimomura, Masaki Nambata, Atsuya Ishikawa +4
Although autonomous driving systems demonstrate high perception performance, they still face limitations when handling rare situations or complex road structures. Such road infrast…
Bidirectional Action Sequence Learning for Long-term Action Anticipation with Large Language Models
Yuji Sato, Yasunori Ishii, Takayoshi Yamashita
Video-based long-term action anticipation is crucial for early risk detection in areas such as automated driving and robotics. Conventional approaches extract features from past ac…
Panoramic Distortion-Aware Tokenization for Person Detection and Localization in Overhead Fisheye Images
Nobuhiko Wakai, Satoshi Sato, Yasunori Ishii +1
Person detection in overhead fisheye images is challenging due to person rotation and small persons. Prior work has mainly addressed person rotation, leaving the small-person probl…
