Abstract
Figure 1: (a) Top: Photograph taken in a dark environment, the image is noisy and/or blurry. Bottom: Flash photography provides a sharp but flat image with distracting shadows at the silhouette of objects. (b) Inset showing the noise of the available-light image. (c) Our technique merges the two images to transfer the ambiance of the available lighting. Note the shadow of the candle on the table. Our technique enhances photographs shot in dark environments by combining a picture taken with the available light and one taken with the flash. We preserve the ambiance of the original lighting and insert the sharpness. We use the bilateral filter to decompose the images into detail and large scale. We reconstruct the image using the large scale of the available lighting and the detail of the flash. We detect and correct flash shadow. Our output combines the advantages of available illumination and flash photography.
