Digital photography with flash and no-flash image pairs
ACM Trans. Graphics (SIGGRAPH), 23(3), 2004.
Combining detail of a flash image with ambient lighting of a non-flash image.
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.
Equation (9) in the paper has a typo; it should be
Ap / Δp”.
I really like the image deblurring work of
Yuan et al 2007 which uses a blurred/noisy

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.
