Abstract

<p>In this paper, we propose the concept of “Person Re-detection”, which is a person detection method based on prior knowledge of each detection target. We also introduce an implementation of the concept for the task of distant person detection from in-vehicle camera video. We focus on the fact that some other vehicles around the own vehicle can observe and detect people before the own vehicle observes them. By sharing images of the detected people among the vehicles, the own vehicle can use them as prior knowledge for detecting them. Results of applying the proposed method to a dataset obtained by an in-vehicle camera demonstrate that the accuracy of person detection can be significantly improved based on</p><p>prior knowledge of the people to be detected.</p>
