17 Description: image blending tools
18 Enblend is a tool for compositing images. Given a set of images that overlap
19 in some irregular way, Enblend overlays them in such a way that the seam
20 between the images is invisible, or at least very difficult to see. It can,
21 for example, be used to blend a panorama composed of several images.
22 .
23 It uses a Burt & Adelson multi-resolution spline. This technique tries to
24 make the seams between the input images invisible. The basic idea is that
25 image features should be blended across a transition zone proportional in
26 size to the spatial frequency of the features. For example, objects like
27 trees and windowpanes have rapid changes in color. By blending these
28 features in a narrow zone, you will not be able to see the seam because the
29 eye already expects to see color changes at the edge of these features.
30 Clouds and sky are the opposite. These features have to be blended across a
31 wide transition zone because any sudden change in color will be immediately
32 noticeable.
33 .
34 Enfuse blends differently exposed images of the same scene into a nice output
35 image, without producing intermediate HDR images that are then tonemapped to a
36 viewable image. This simplified process often works much better and quicker
37 than the currently known tonemapping algorithms.
38 .
39 The exposure blending is done using the Mertens-Kautz-Van Reeth exposure
40 fusion algorithm. The basic idea is that pixels in the input images are
41 weighted according to qualities such as proper exposure, good contrast, and
42 high saturation. These weights determine how much a given pixel will
43 contribute to the final image.
44 .
45 Both Enblend and Enfuse do not align images for you. Use a tool like Hugin or
46 PanoTools to do this. The TIFFs produced by these programs are exactly what
47 Enblend and Enfuse are designed to work with.
