raw_dead_pixel_mask — GFX2D isp op

• 数据种类:image2d → image2d

• 调用: import fullseye as fs; fs.ledger.raw_dead_pixel_mask(raw, threshold=0.1)(要直接调用实现,import gfx2d; gfx2d.raw_dead_pixel_mask(raw, threshold=0.1);从台账取用则 opsgfx2d.get("raw_dead_pixel_mask"))

用法

坏点图:与全部 8 个同色邻域朝同一方向偏离超过阈值的像素。

> 以下的详细说明为原文 —— 摘要与标题已翻译。

"Every neighbour, same sign" is what separates a defect from an edge: at an

edge some same-colour neighbours are on the pixel's own side. The rule is

the one openISP documents for its DPC stage; here it is pattern-free

because same-colour neighbours are simply the pixels two steps away.

Ground truth: dead pixels planted in a smooth frame are recovered exactly

(no misses, no false alarms) while a hard edge produces none.

Raises `ValueError: bad *raw* or a *threshold* outside (0, 1]`.
