Exercise $3\mathrm{.}11$ Using the various contrast enhancement and dynamic range manipulation

approaches presented throughout this chapter, investigate and make a selection of transforms

to improve the contrast in the example image $$AT$31$m$401.$tif$.$ Once you have

achieved a suitable contrast for this example image, extract the corresponding histogram

distribution of the image $($Example $3\mathrm{.}13)$ and apply it to the other images in the sequence

$($AT$31$m$402.$tif$,...$AT$31$m$409.$tif$,$AT$31$m$410.$tif$)$ using histogram matching

$($Example $3\mathrm{.}20).$ Are the contrast settings determined for the initial example image suitable

for all of the others? What if the images where not all captured under the same conditions?

Here, we see the use of histogram matching as a method for automatically setting the

dynamic range adjustment on a series of images based on the initial determination of

suitable settings for one example. Where else could this be applied?
