Hi, So I was reading a paper on implementation of MLV filters which belongs to a broder class of value-and-criterion filters. I read this paper "A morphology-based filter structure for edge-enhancing smoothing<http://ieeexplore.ieee.org/xpl/articleDetails.jsp?reload=true&arnumber=413627> " It elaborates on the advantages over the median filter or morphological opening. It essentially exhibits edge-enhancing noise smoothing behaviour. Best of all it can be extended to 3D easily. I think it would be a good addition to the already present filter implementations on skimage. What do you guys think about this ? Chintak
