Hi all,


I'm using Color Deconvolution with FIJI and there's something I don't fully understand.


The red, green and blue colors of a RGB image use 8 bits each, which have integer values from 0 to 255, right? Therefore, what is the meaning ofhaving values with 6 digits after the decimal point?

For example when I use Color Deconvolution with “From ROI” option, I get the Vector Matrix with values of e.g.


Red: 9.290228
Green: 8.5856
Blue: 11.380588

Are all those non-integer digits the result of average-like operations over a number of pixels with different, integer RGB values?

Best,
Rodrigo
