Widget that allows for easy selection of a features function and its options. It also has a ‘preview’ tab for visual inspection. It returns a list of length 1 with the selected features function closure.

Returns:features_function (list of length 1) – The function closure of the features function using functools.partial. So the function can be called as:
features_image = features_function[0](image)


The widget can be invoked as

from menpo.feature import features_selection_widget
features_fun = features_selection_widget()

And the returned function can be used as

import menpo.io as mio
image = mio.import_builtin_asset.lenna_png()
features_image = features_fun[0](image)
