I think that you might have misunderstood what has been requested. It is common practice to define a region of interest on an object and to collect several measurement points from this ROI. By examining the spectra and the rate of change in Lab values you can be reasonably certain whether or not the colorant is the same, and to then create an average of the colour change data to account for variance.
I believe what is asked for, or at least what I want the from the software, is the ability to group samples that I believe are the same material and then display the average delta L a b and E for that group of samples.
I propose that you make a 3 tier sample grouping in the ageing tab.
Tier one “group” which would correspond to object name,
Tier two “region of interest” which would correspond to a particular coloured region
Tier three “sample iteration” which would correspond to individual measurement points
Tier three would include a check box so that the user can select/deselect sample points for the average and SD calculations. If two or more samples are selected a new plot appears on the graph, “Average of Tier 1-Tier 2-Tier 3”
The users could then select to use the averaged plots in the report.
For me this would increase the throughput of using MFT by many fold and would make me a much happier end user as well as distributor.
