Object Detection Difficulty: Suppressing Over-aggregation for Faster and Better Video Object Detection

1 code implementation22 Aug 2023 Bingqing Zhang, Sen Wang, Yifan Liu, Brano Kusy, Xue Li, Jiajun Liu

The ODD score enhances the VOD system in two ways: 1) it enables the VOD system to select superior global reference frames, thereby improving overall accuracy; and 2) it serves as an indicator in the newly designed ODD Scheduler to eliminate the aggregation of frames that are easy to detect, thus accelerating the VOD process.

InvisibiliTee: Angle-agnostic Cloaking from Person-Tracking Systems with a Tee

1 code implementation15 Aug 2022 Yaxian Li, Bingqing Zhang, Guoping Zhao, Mingyu Zhang, Jiajun Liu, Ziwei Wang, JiRong Wen

After a survey for person-tracking system-induced privacy concerns, we propose a black-box adversarial attack method on state-of-the-art human detection models called InvisibiliTee.
