raw_dead_pixel_correct — GFX2D `isp` op

• Data kinds: image2d → image2d

• Call: import fullseye as fs; fs.ledger.raw_dead_pixel_correct(raw, threshold=0.1) (to call the implementation directly, import gfx2d; gfx2d.raw_dead_pixel_correct(raw, threshold=0.1); from the registry, opsgfx2d.get("raw_dead_pixel_correct"))

Usage

Replace every dead pixel (:func:raw_dead_pixel_mask) by the median of its 8 same-colour neighbours; every other pixel is returned bit-for-bit.

The median rather than the mean so that two adjacent defects do not pull

each other's replacement. Ground truth: in a smooth frame with planted

defects the corrected values are within the neighbours' range and the

untouched pixels are identical to the input.
