Hi,
Could somebody point me to a way in which I could apply a Mexican hat
filter to an image (with a controllable width)? Does somebody know of a
piece of code floating around that can do this and that is compatible
with PIL?
Or, in absence of this, could somebody tell me how I can do Gaussian
blurring (with a controllable width). I can approximate the Mexican hat
with a DOG. I found the pil_usm module. But this is not compiled for
python > 2.1 (I use 2.5).
Greetings,
Dieter
