This paper presents an effective method to enhance the quality of dim light surveillance via gradient fusion. We simply take the advantage that surveillance cameras capture a large quantity of valuable information at the same viewpoint during the day. And it can be used to make the video at night easier to perceive. Based on a gradient domain technique, all the important local perceptual cues from...
High noise level from darkness and low dynamic range are two characteristics of low light surveillance image that severely degrade the visual quality. Traditional low light image enhancement methods merely use the 2D cues without the depth information of the scene. Recently, the depth based image enhancement methods are proposed to enhance the depth perception of the image. However, these depth based...
