Figure 1 : Automatic context enhancement of a night time scene. The image is reconstructed from a gradient field. The gradient field is a linear blend of intensity gradients of the night time image and a corresponding day time image of the same scene. Abstract We present a class of image fusion techniques to automatically combine images of a scene captured under different illumination. Beyond providing digital tools for artists for creating surrealist images and videos, the methods can also be

The context is automatically captured from a fixed camera and inserted from a day-time image (of the same scene). Our approach is based on a gradient domain technique that preserves important local perceptual cues while avoiding traditional problems such as aliasing, ghosting and haloing. We presents several results in generating surrealistic videos and in increasing the information density of low quality nighttime videos.
