Logging pixel counts

[Hannah C]

Hi there

I am very new to to image j

My problem is that I have a load (5447) of 8 bit images and need to record the name of the image file and the count of the 139 grey value (row 140 of 256) in a single output table.

Thanks

Hannah

Run Process>Batch>Macro, click "Input..." and select the directory containing the files, paste

  if (i==0)
     print("\\Clear");
  getRawStatistics(n,mean,min,max,sd,hist);
  print(getTitle+"\t "+hist[139]);

into the macro box, then press "Process". When finished, use the "Log" window's File>Save As command to save the table.

Wayne, is "i" a running index used in Batch>Macro used to track the
number of images that have been processed? Is it automatically incremented?
