Hi,

My goal with the thresholded blur is making "edge aware" averaging. All the pixels very different to the center's one (possible edge) are completely discarded (not zeroed) from the average. For my purpose the center must be excluded also.

Convolution3D and (I suppose) Deen don't discard pixels, limit it to the threshold instead. And process the center also. The result is different, mostly if the center is very different from neighbours (isolated dots).
