Object detection in remote sensing images has received significant attention for a wide range of applications. However, traditional unimodal images, whether based on visible light or infrared, have limitations that cannot be ignored. Visible are susceptible to ambient lighting conditions, and their accuracy can greatly reduced. Infrared often lack rich texture information, resulting high false-detection rate during target identification classification. To address these challenges, we propose...
