Hi,
closest equivalent of the lua script in imagemagick:

convert -page +1+1 test.png -background none -flatten test2.png ;
convert test.png test2.png -compose difference -composite -colorspace RGB -threshold 254 difference_gray.png

About four times faster than lua script above!
No fx functions ...

Hi,
found an image filter that does nearly the thing i want to do:

convert input.jpg -colorspace Gray -lat 35x35-1.8% -median 3x3 -morphology Dilate Plus:2 output.jpg

That command is already relatively fast and can output interesting images.

As you might notice its not exactly an image detector ...
