It's not neighbor *search*, it's applying a function over an (arbitrary chosen and weighted) moving neighborhood in an nd array.

It would be useful for the author of the PR to post a detailed comparison of this functionality with scipy.ndimage.generic_filter, which appears to have very similar functionality.
