Discrete Color Algorithm Configuration</h2>
|
||
|
|
The discrete color algorithm is very simple in the case of
|
||
|
|
non-overlapping
|
||
|
|
discrete configuration. It simply uses a color table in much the
|
||
|
|
same way as SCALAR and VECTOR use color tables. The algorithm
|
||
|
|
becomes
|
||
|
|
more complicated when the discrete element contains overlapping
|
||
|
|
information.</div>
