Fwd: Platform for filters development

(I think I missed the attachment) Attached here a concept code showing my attempt to produce in improved (over ndimage.generic_filter) platform for filters development. The code is very preliminary and needs a lot of extension as well as rewrite. My main questions are: 1. Is there is already a mature package for this purpose? 2. Is there is need for such a module inside scikits? Any comment is welcome. Nadav
