i've tried several versions of imagemagick, e.g. 6.6.4, 6.6.7, 6.7.2. (Windows, MacOS) and the command "-adaptive-sharpen" does not seem to have any effect at all.
is there something i am missing or is it simply broken?
example
"convert picture.tif -resize x500 -adaptive-sharpen 0x1 picture.jpg"
adaptive-sharpen not working?

Seems to be the case:
convert rose: -adaptive-sharpen 0x5 rose_as5.png
compare -metric rmse rose: rose_as5.png null:
0 (0)
convert rose: -adaptive-blur 0x5 rose_ab5.png
convert rose_ab5.png -adaptive-sharpen 0x5 rose_ab5_as5.png
compare -metric rmse rose_ab5.png rose_ab5_as5.png null:

I suggest you report this on the bugs forum.
