            Bug ID: 1245
           Summary: Difference in pixel integration
           Product: Fiji
           Version: unspecified
          Hardware: PC
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P4
         Component: Plugins
          Assignee: imagej-bugs at imagej.net
          Reporter: jhatcher at wisc.edu

In the uploaded image, there are two light spots and two dark spots. If I do
pixel integration on only the two light spots, I get
1) 10345.196
2) 11823.095.
If I then reset and integrate all 4 spots using the same selection box, I get
1) 3921.276
2) 4440.347
3) 15793.388
4) 16380.217

Why would the lighter spots integrate so much less when denser spots are
included in the measurements?
