xsk2_wiener — 2D restoration op

Data kinds: imageimage

Call: fullseye.apply(img, "xsk2_wiener", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

Usage

Wiener deconvolution (deblurring using a known point spread function). Calls `skimage.restoration.wiener`.

> The detailed description below is the original text — the summary and the headings are translated.

PSF はガウシアン形状を仮定して自前生成し、a が PSF の広がり

(標準偏差 `0.5 + 1.5*a`、5x5 窓)を振る。b がバランス項

(`0.05 + 0.5*b`。ノイズ対信号比の逆数に相当し、大きいほどノイズ

抑制寄りになる)を振る。**入力画像のボケが実際にこの想定ガウシアン

PSF と一致している場合にのみ有効**で、PSF の形が違うとリンギングや

復元失敗が出る。
