Rawtherapee 'Contrast by detail levels'

[robertkjr3d]

How do I mimic this functionality in Magick.NET?
0 is Finest 4 is (Coarsest)
When messing around with particular CR2s. I find that I can find more detail with this contrast function in my images. Particularly 3 and 4 (coarsest). But I don't know what to look for in Magick.NET, for anything similar.

What is the function you need to mimic? Perhaps is you give some detail and background, someone might be able to help. Contrast is not a well defined unique entity. There are many variations. IM has -contrast and -brightness-contrast and -level and -sigmoidal-contrast and contrast-stretch and several others. See http://www.imagemagick.org/script/comma ... ptions.php and http://www.imagemagick.org/Usage/color_mods/

IM does not have any wavelet decomposition/recomposition tool, currently.

The closest you could come in IM is to do Gaussian/Laplacian Pyramid processing to get multi-resolution levels. see http://en.wikipedia.org/wiki/Gaussian_pyramid. IM has Gaussian blurring and Laplacian sharpening.

Some while ago I tried to script Haar Wavelets (unix bash shell script), but never finished it.

And Magick.NET I can't seem to find laplacian sharpen.

And Magick.NET I can't seem to find laplacian sharpen.

In the command line it is part of -morphology/convolution. See http://www.imagemagick.org/Usage/convolve/

I've seen those neat command-line scripts. Except.. how to execute in Magick.NET?
image.Execute does not. What is the trick I'm missing? Is there a documentation I'm missing?

My scripts only work on Unix/Linux/MacOSX and Windows with Cygwin. Sorry.

Which script do you want to translate to .NET? I might be able to help you.
