gray op• Data kinds: image → image
• Call: fullseye.apply(img, "xcv_detail_enhance", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
OpenCV's detailEnhance (detail enhancement).

エッジ保存平滑化をベースに、平坦部は滑らかに保ったまま微細な
ディテール(テクスチャ)のコントラストを持ち上げる。
`a が空間範囲 sigma_s を 10〜50 で振る。b` が色差許容
`sigma_r を 0.1〜0.4 で振る。xcv_edge_preserving` と同系の
処理だが、こちらは細部を「消す」のではなく「強調する」方向のフィルタ。
