Dual Attention Feature Fusion for Visible-Infrared Object Detection
ARTIFICIAL NEURAL NETWORKS AND MACHINE LEARNING, ICANN 2023, PT VII(2023)
Abstract
Feature fusion is an essential component of multimodal object detection to exploit the complementary information and common information between multi-source images. When it comes to visible-infrared image pairs, however, the visible images are prone to illumination and visibility and there may be a lot of interference information and little useful information. We suggest performing common feature enhancement and spatial cross attention sequentially to solve this problem. For this purpose, a novel Dual Attention Transformer Feature Fusion (DATFF) module which is designed for feature fusion of intermediate feature maps is proposed. We integrate it into two-stream object detectors and achieve state-of-the-art performance on DroneVehicle and FLIR visible-infrared object detection datasets. Our code is available at https://github.com/a21401624/DATFF.
