Return the list of ISET color descriptions
[cfaOrdering, cfaMap] = sensorColorOrder([format])
Purpose:
The function stores how ISET associates color filter names with color
values. The cfaOrdering is a list that describes letters associated
with color names. The cfaMap are the color values describing these
names.
The first letter in a filter name (e.g., rStanford) is a hint about the
color appearance of that filter (e.g., red). The associations between
the hint ('r') and color appearance are contained here. The letter 'r'
is associated with the color map entry of (1,0,0). Other filter names
used by the simulator are given plausible color hints:
The set of color hints are r,g,b,c,y,m,w(hite).
There are a few other free color names that are undefined, (u,x,z,o)
for experimenting. These are given color map entries of
u -> [.4, .7, .3]; x -> [.7 .5 .3]; z -> [.2 .5 .8] and o -> [.5 .5 .5];
The set of filter names in an ISA have distinct olor hints. So, using
rStanford, gStanford is OK; but do not use rStanford, rSony. Even if
both filters are red, use a different color hint, say rStanford,
xSony.
The normal format used to return the list of color letters is a cell array. If the
function argument format is set to 'string', then the cfaOrdering is
returned as a string.
Example:
[c,mp] = sensorColorOrder('string');
[c,mp] = sensorColorOrder;
