No-Flash Image

Detail Transfer with Denoising

Abstract

Digital photography has made it possible to quickly and easily take a pair of images of low-light environments: one with flash to capture detail and one without flash to capture ambient illumination. We present a variety of applications that analyze and combine the strengths of such flash/no-flash image pairs. Our applications include denoising and detail transfer (to merge the ambient qualities of the no-flash image with the high-frequency flash detail), white-balancing (to change the color tone of the ambient image), continuous flash (to interactively adjust flash intensity), and red-eye removal (to repair artifacts in the flash image). We demonstrate how these applications can synthesize new images that are of higher quality than either of the originals.

Results

  • Detail Transfer and Joint Bilateral Filtering - view crops, view full-resolution TIFFs

    The crops can be viewed in the browser. The full-resolution images require a separate viewer. Note that the cropped images are JPEG compressed and may contain small blocking artifacts. The full-resolution images are uncompressed, but therefore rather large. Some of these images may require gamma adjustments to your monitor to see the noise. Images tagged with "bilateral" were computed using a basic bilateral filter.
     
  • White-balancing - view images
     
  • Continuous Flash - view images, view video (Microsoft MPEG4 AVI, no sound)
     
  • Red-eye - view images
