Adaptively smoothing astronomical images with adaptsmooth

 

adaptsmooth is a code developed by Stefano Zibetti at MPIA (Heidelberg) to perform adaptive smoothing of astronomical images, so to enhance their signal to noise ratio with a minimum loss of effective resolution and, of course, by keeping the photometric fluxes unaltered.


Here below is an example on the color composite image (H2, Br-gamma, Pa-beta) of the nebula NGC2024, after adaptsmooth-ing (left panel) and in the original images (right panel).

For more information about the algorithm and the code please take a look at the paper on astro-ph arXiv:0911.4956.

You can download the code (current version V.2.7.1 15.11.2010) from this link, but first check the readme file!
