Hello and thanks for your help
Looking through the documentation I found the function medianblur
it seems to apply the median of a sector of an image defined by a square of some size.
My first question is: Is there something similar but for mean not median??
--
my second question is , what if afterwards I want to apply some operation to my original image and to the mean image. (substracting, multiplying by some scalar, adding) . Can I do this just with +.* /. as if images were just simple matrices... (which they are, no???)
Thanks a thousand
