smoothing op• Data kinds: image → image
• Call: fullseye.apply(img, "xcv3_denoise_tvl1", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])
> This operator's description has not been translated yet. The original text follows as it is.
全変動 L1 ノイズ除去(OpenCV `cv2.denoise_TVL1`、Primal-Dual アルゴリズム)。エッジを保ちながらノイズを除去する全変動最小化に基づく手法で、通常のガウシアン平滑化よりエッジがシャープに残る。
`a は正則化項の重み lambda(0.3+2.7*a で 0.3〜3.0。小さいほど強く平滑化される)、b は反復回数(int(10+40*b)` で 10〜50)を振る。8bit 量子化を経由するため入力の float64 精度は失われる。
