Abstract: Pedestrian detection is an active area of research with challenge in computer vision. In recent years, pedestrian detection based on machine learning has achieved great development. However, since data of various application scenes are under different data distributions, the performance of a well-trained detector drops significantly in a new scene. In order to avoid the effort of manual labeling and make full use of the original detector and labeled samples, pedestrian detection based on transfer learning has attracted more and more attention. This paper reviews pedestrian detection based on transfer learning, involving sample collection, transfer learning and detector optimization. Recent research on this topic is summarized and compared in different ways. Future directions are discussed.

Key words: pedestrian detection, detector, transfer learning, domain adaptation
