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.

Nothing new here ! Merging SPOT and Landsat imagery is/was the topic of the following study and poster. Detail from a SPOT 5meter resolution panchromatic image and multi-spectral data from a Landsat 30meter Bands 4, 5 & 6 RGB image were combined. This was back in about 1991 I think. The following web page shows the poster I made for the work done through the Wildlife Spatial Analysis Lab at The University of Montana. http://www.wru.umt.edu/posters/1000/BigFork.SPOT.Compare.html.

Hah! When I saw that this was from Microsoft, I naturally wondered who they stole it from. Now we know!
