DESCRIPTION

IMMEDIAN is a MIRIAD task which performs a median filter over an image. No subregion can be selected, the whole image is processed. See also ELLINT for a median filter in elliptical rings. Masking information is properly processed: if any of the associated pixels has been masked out, they will not be used in the median filter. Edge pixels are not filtered and passed onto the output image unchanged.  

PARAMETERS

in
The input image. No default.
out
The output image. No default. Note: Nasty things can happen to 4D+ datasets.
size
Half the box size. The filtering box will be square and have a size of 2*SIZE+1, and will thus always have an odd number of pixels centered on the pixel to be filtered. Edge pixels are left untouched.
