xsk3_corner_fast — 2D edges op

Data kinds: imageimage

Call: fullseye.apply(img, "xsk3_corner_fast", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

> This operator's description has not been translated yet. The original text follows as it is.

FAST コーナー検出(skimage `feature.corner_fast`)。中心画素の周囲の円周上の画素と比較し、連続して明るい/暗い画素が一定数以上続く場所をコーナーとして検出する高速な手法。結果は最大絶対値で正規化した応答マップ。

`a は連続画素数のしきい値 n(9+int(a*3) で 9〜12)、b は輝度差のしきい値(0.05+0.2*b` で 0.05〜0.25)を振る。
