NAMA
light_correct - correct illumination errors on set of images
SINOPSIS
light_correct kelabu image1 image2 image3 ...
DESCRIPTION
The first argument should be an image of a piece of grey card, subsequent arguments should
be images taken with the same lighting set-up which need correcting. The corrected images
are written to files prefixed with "ic_".
For example, suppose you have a directory with the following files in:
example% ls
dat1.1.v dat1.2.v dat2.1.v dat2.2.v dat3.1.v dat3.2.v
dat4.1.v dat4.2.v grey.v
then run light_correct like this:
example% light_correct grey.v dat*.v
to generate this:
example% ls
dat1.1.v dat1.2.v dat2.1.v dat2.2.v dat3.1.v dat3.2.v
dat4.1.v dat4.2.v grey.v
ic_dat1.1.v ic_dat1.2.v ic_dat2.1.v ic_dat2.2.v ic_dat3.1.v
ic_dat3.2.v ic_dat4.1.v ic_dat4.2.v
light_correct works by smoothing out the grey card image, finding grey-mean/pixel for each
point, and then multiplying the result by all the following images. It also removes any
.desc files it generates, to avoid problems with im_global_balance(3).
