morphology op• Data kinds: image → image
• Call: fullseye.apply(img, "xsk3_area_closing", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
Area closing (skimage `morphology.area_closing`). A size-based morphological operation that fills in only dark regions (dips) with area below a threshold - unlike ordinary closing, it selects targets by the area of the connected component rather than the shape of the structuring element.
