Introducing color in coding<br />
Examples<br />
• Allowing colors in coding is the same as<br />
augmenting code basis. This gives us more words<br />
with the same length.<br />
• If the scene changes the color <strong>of</strong> projected light,<br />
then information can be lost.<br />
• Reflectivity restrictions (neutral scene colors) have<br />
to be imposed to guarantee the correct decoding.<br />
