isp op• 数据种类:image2d → rgb
• 调用: import fullseye as fs; fs.ledger.raw_demosaic_bilinear(raw, pattern='RGGB')(要直接调用实现,import gfx2d; gfx2d.raw_demosaic_bilinear(raw, pattern='RGGB');从台账取用则 opsgfx2d.get("raw_demosaic_bilinear"))
用纯 NumPy 的双线性插值把 Bayer 马赛克变成 (H, W, 3) RGB。

Red and blue occupy one pixel in four, so a missing value is the mean of
the measured neighbours (`[[1,2,1],[2,4,2],[1,2,1]]/4` on the masked
plane); green occupies two in four (`[[0,1,0],[1,4,1],[0,1,0]]/4`). The
border mirrors the mosaic two pixels out with a non-duplicating
reflection, which keeps the 2x2 phase, so a uniform field is exact up to the
edge. This is the same estimate the OpenCV bridge `cfa_to_rgb` makes with
`cv2.COLOR_Bayer*2RGB`, without the 8-bit round trip and without OpenCV.
Ground truth: three affine planes mosaicked and demosaicked come back to
1e-12 away from the border (a bilinear estimate of an affine field is the
field). Bilinear is the textbook baseline: it blurs colour edges into
zipper artefacts; edge-directed methods are not provided here.
Raises `ValueError`: bad *raw* or *pattern*.
