Research paper: Scale-Aware Fast R-CNN for Pedestrian Detection, (First Author: Dr. Li Jianan; Corresponding Author: Professor Xu Tingfa), published in IEEE Transactions on Multimedia, the journal published by the American Institute of Electrical and Electronics Engineers (IEEE), The impact factor in the past 5 years was 5.551.
The thesis aims at the different feature patterns of pedestrian targets at different scales, and the intra-class differences caused by the input target scale changes will greatly increase the learning difficulties and challenges of the target detection model. The thesis takes the strategy of treating different objectives differently, while sharing the underlying common features to ensure computational efficiency, the exclusive network branch is used to capture the unique high-level features of different scale targets. Independent prediction and scale adaptive fusion are performed to enhance the model's robustness to input scale changes as well. This method is simple and easy to implement, at the same time it can be effectively applied to pedestrian detection in real complex scenes. More importantly, this method provides an effective and practical new idea to improve the robustness of the detection model against input changes, and is widely used in other tasks in the field of computer vision.
