Sample every module centre (bilinear) through the located homography and threshold globally at the midpoint of the dark and light means (initial split at the midpoint of the 5th/95th percentiles, then two mean-midpoint updates).
Returns reflectance (R, C), modules (R, C) uint8 dark = 1,
threshold, homography, centers (R, C, 2) px (row, col).
