boofcv.alg.fiducial.calib.ecocheck.ECoCheckLayout

public class ECoCheckLayout
extends Object

Defines bit sampling pattern for different sized grids. Damage to markers tends to occur in local regions and not as random bit errors. ECC can only fix errors in a per-word basis (8-bits), so it makes sense to cluster all the points in a word as close to each other as possible. A simple formula is used to select the layout of bits in the N by N grid that attempts to group bits in the same word together. A naive layout would cause a small error in a local region to damage multiple words, crippling error correction.
