CATEGORIES

map analysis  

DESCRIPTION

IMSHARP is a MIRIAD task which sharpens an image. No sub region can be selected, the whole image is processed. Masking information is properly processed though: if any of the associated pixels has been masked out, so will be the corresponding pixel in the output image. Other methods to sharpen images: use SMOOTH with norm=0.0 and divide the smoothed map by the original map using MATHS (unsharp masking). Also: Shift or rotate an image, and subtract it from the original. Good for (non)axysymmetric features resp.
