Improvement of On-Road Object Detection Using Inter-region and Intra-region Attention for Faster R-CNN.

In this paper, we incorporate the attention module and the lambda layer into the existing object detection method, Faster R-CNN, to improve its detection accuracy. We propose three methods that incorporate mechanisms based on the attention module to capture the relationship between object candidate regions within an input frame, or a mechanism based on the lambda layer to improve the feature representation within each candidate region. We evaluated the performance of the proposed methods on BDD100K, which includes diverse scene types, weather conditions and times of the day. The results show that the detection accuracy of the proposed methods are improved compared to Faster R-CNN.
