export intensity value

[Ye Chen]

Hello,

Is there plugin available to export each pixel intensity value of a chosen
ROI  ( a matrix) to a txt file or excel file?

Thanks

I plugin is not needed. Use Image>Duplicate to create an image  
containing just the contents of the selection, then export to a tab-
delimited, excel-compatible text file using File>Save As>Text ImageJ.  
These steps can be automated using the following macro:

   setBatchMode(true);
   run("Duplicate...", "title="+getTitle+"-copy");
   saveAs("Text Image");
   close();
