xcv_inpaint — 2D `restoration` op

• Data kinds: image → image

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

xcv_inpaint: input → output

*The figure is the actual output on a synthetic 128×128 input. Left: input, right: output. Point clouds are drawn as a top-down scatter (brightness = z), 1-D series as a line plot, volumes as the maximum-intensity projection along z, videos as the middle frame, complex images as magnitude; return values that are not pictures are shown as the values themselves.*

*Knob a does not change the output (measured: identical at 0.1 / 0.5 / 0.9).*

*Knob b does not change the output (measured: identical at 0.1 / 0.5 / 0.9).*

On other images (synthetic scene / photo / coins. Top row: inputs, bottom row: their outputs. Knobs at default):

▸ xcv_inpaint: other inputs (docs site)

*The 4th column is a colour (H,W,3) input. This op handles colour without crossing channels (it does not convolve the colour channel as a third spatial axis).*

Usage

Inpainting that estimates and fills in missing regions.

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

8bit 変換後、極端に明るい(>235)/暗い(<20)画素を「欠損」とみなして

自動マスクし、OpenCV の Telea 法(高速マーチング法ベース、

`cv2.INPAINT_TELEA)で周囲から埋める。xsk_inpaint`

(biharmonic 法)と同じ発想の別アルゴリズム版。

半径 3 画素の近傍を使う(固定)。`a, b` は未使用。しきい値が

固定のため、本来意味のある白飛び/黒つぶれ画素まで埋められてしまう

場合がある。

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
