sk_slic — 2D segmentation op

Data kinds: imageregion

Call: fullseye.apply(img, "sk_slic", 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.

SLIC(Simple Linear Iterative Clustering)によるスーパーピクセル分割。色(ここではグレー値)と座標を合わせた空間で k-means クラスタリングを行い、ほぼ均等な大きさの領域に分割する。ここでは分割結果の境界線を領域として返す。

HALCON に直接対応するものは無い。実装は `segmentation.find_boundaries(segmentation.slic(v, n_segments=int(10+80*a), channel_axis=None))` —— a はおおよそのセグメント数を 10〜90 に振る(大きいほど細かく分割される)。b は未使用。
