<h2><b>spectro/average</b></h2>
|

<h3>Summary</h3>
|
|
Average or merge two or more <a href="File_Formats.html#.ti3">.ti3</a>
|
|
measurement files.<br>
|
|
If only one input file is provided, then for output or display
|
|
device test charts all the patches with the same device values will
|
|
be average together,<br>
|
|
while for input device test charts all the patches with the
|
|
same PCS values will be averaged together.<br>
|

All keywords and other table data will be taken from the first input
|
|
file. By default the input files are averaged, but they can be
|
|
merged by using the <span style="font-weight: bold;">-m</span>
|
|
flag.<br>
|
|
<br>
|
|
The fields must be the same and in the same order.<br>
|
|
For averaging output or display device test charts, the device
|
|
values must be the same and in the same order.<br>
|
|
For input device test charts, the PCS values must be the same and in
|
|
the same order.<br>
|
|
<br>
|
|
If the <b>-e</b> option is used, then the independent median (i.e.
|
|
Marginal median) of the field values is used, rather than the
|
|
average. <br>
|
|
<br>
|
|
If the<b> </b><b>-g</b> option is used, then <a
|
|
href="https://en.wikipedia.org/wiki/Geometric_median">Geometric
|
|
Median</a> of PCS values (output or display) is computed in their
|
|
encoded space (i.e. XYZ or L*a*b*).<br>
|
|
For input type device test charts, the Geometric mean of 3 channel
|
|
device values is computed.<br>
|
|
<br>
|
|
If the <b>-L</b> option is used, then Geometric Median of PCS
|
|
values is computed in L*a*b* space.<br>
|
|
This option is ignored for input device test charts.<br>
|
|
<br>
|
|
If the <b>-X</b> option is used, then Geometric Median of PCS
|
|
values is computed in XYZ space.<br>
|
|
This option is ignored for input device test charts.<br>
