texture op• Data kinds: image → image
• Call: fullseye.apply(img, "xsk_meijering", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
Meijering neuriteness filter. Applies `skimage.filters.meijering` at three scales (sigma=1,2,3) to enhance thin curvilinear structures (such as blood vessels or neurites) (like the Frangi family, it computes ridge-likeness from the eigenvalues of the Hessian matrix, but Meijering also responds strongly at branch points).
