Abstract: In this paper, we present a novel low-light image enhancement method calleddark region-aware low-light image enhancement (DALE), where dark regions areaccurately recognized by the proposed visual attention module and theirbrightness are intensively enhanced. Our method can estimate the visualattention in an efficient manner using super-pixels without any complicatedprocess. Thus, the method can preserve the color, tone, and brightness oforiginal images and prevents normally illuminated areas of the images frombeing saturated and distorted. Experimental results show that our methodaccurately identifies dark regions via the proposed visual attention, andqualitatively and quantitatively outperforms state-of-the-art methods.
