AOI: Atmospheric Optical Image Enhancer
'AOI' is an image processing application, mainly for enhancing photographs of atmosphric optical phenomena like halos. Dropping or pasting an image onto window and selecting a recipe, then please push the 'start' button to process the image. The result image can output to file or copy-and-paste to other applications.
(Tuned) B-R processing with automatic adjustment of the 'constant' parameter. The ratio parameters for R, G, B are pre-defined, which values exceed the value you can set on Photoshop/Paint Shop Pro. Approximately, it is "Blue channel minus Red channel" process. This process reduces contrast of clouds and enhance (colored) halos in a photo.
A variation of autoBR. Approximately, it is "Red channel minus Green channel" process. Try it for an image for which the 'autoBR' seem not to work well.
Unsharp mask with bigger parameters (well-known method to enhance minute difference of halo colors and/or intensities). The weak point is that it also enhances edge of silhouettes of objects hiding the light source. The target image will be shrinked.
A revised unsharp mask to defeat the weak point, which is less sensitive for larger difference of colors and intensities. The target image will be shrinked.
