| The new
coding strategy |
|
|
| Example: |
|
| n=4,
m=3 |
|
|
|
|
|
|
| Given n different values |
||||
| of Hue and a window |
||||
| size
of length m |
||||
|
|
|
|
|
|
|
| A pattern with 2nm stripes
is defined |
||||||
| with a square Luminance profile with |
||||||
| alternating full-illuminated and half- |
||||||
| illuminated stripes |
||||||
|
|
|
|
|
| The
pattern is divided in n periods |
||||
| so that all the full-illuminated
stripes |
||||
| of every period share the same Hue |
||||
|
|
|
|
|
|
|
| The half-illuminated stripes of every |
||||||
| period are coloured according to a |
||||||
| De Bruijn sequence of order m-1 |
||||||
| and
the same n Hue values |
