Viewer Plugins -> Passing precalculated arguments

Hi Marcel,

Check out functools.partial, which is a standard function in Python. It allows you to create functions with pre-evaluated arguments:

from skimage.restoration import denoise_tv_bregman

import functools

denoise = functools.partial(denoise_tv_bregman, weight=5, max_iter=10)

# use denoise_tv_bregman with weight and max_iter set:

denoise_plugin = Plugin(image_filter=denoise)
