Hi,
The image inherently contains all the pixel intensities, turning the image into
a results table actually changes nothing, the intensities are not really any
more amenable to quantification.
If your only interest is in the distribution of intensities, then
In a macro
getRawStatistics(nPixels, mean, min, max, std, histogram);
retains all the intensities in a ROI but in an organized form and immediately
provides some basic statistics.
Mean, min, max and std are variables containing the measurement their name
indicates
print(mean) puts the value in the Log window etc
The "histogram" is a variable with multiple entries (bins), each is the number
of pixels with a given intensity in sequential positions.
The whole histogram can be listed by Array.show(histogram);
And can be exported.
You can also read the values from the location/bins in the histogram
V=histogram[position];
The question is what do you want to do with the intensities.

Subject: Intensity of each pixel
Hello,
I would like to know if it is possible to obtain a table with the intensity of
each pixel in a ROI.
If so, how can I do this?
Thank you for your help.
Best regards
Patricia
