FilterErode

Erode (filter): grows dark areas (size > 0) or light areas (size < 0) by a filter-weighted maximum; box is the fastest, gaussian the softest.

Nuke equivalent

Imports from and exports to Nuke's FilterErode. The standard Nuke mask knobs (channels, mask, invert, (un)premult, mix) are mapped too.

Nuke knobs not in this list import as a knob of the same name, or are kept unchanged for export. See .nk import.

Dilate

Erode (fast) (Nuke's Dilate): grows light areas (size > 0) or dark areas (size < 0) by that many pixels with a box minimum / maximum.

Glow2

Glow2: makes bright areas glow — the parts above tolerance are blurred (size, filter, quality as Blur), tinted, saturated, scaled by brightness and added to the image.
