Object Recognition in Atmospheric Turbulence Scenes
2023 31st European Signal Processing Conference (EUSIPCO), 2023 The influence of atmospheric turbulence on acquired surveillance imagery poses significant challenges in image interpretation and scene analysis. Conventional approaches for target classification and tracking are less effective under such conditions. While deep-learning-based object detection methods have shown great success in normal conditions, they ...
