• Call: fullseye.apply(img, "xcv_stylization", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
OpenCV's stylization (painterly/cartoon-like non-photorealistic rendering).
> The detailed description below is the original text — the summary and the headings are translated.
エッジ保存平滑化を使って細部を均しつつ主要な輪郭を残し、平坦な色面と
目立つ輪郭からなるイラスト調の画像を作る(内部で 3ch に変換して処理し、
結果をグレースケールへ戻す)。
`a が空間方向の平滑化範囲 sigma_s` を 20〜120 で振る(大きいほど
広い範囲を均す)。`b が色(輝度)差の許容範囲 sigma_r` を 0.1〜0.5
で振る(大きいほどエッジをまたいで均しやすくなり、平坦化が強まる)。
