No, we shouldn't clutter up the file Exchange with test code like
that.
You can upload your code to http://drop.io. Upload the m-file and
some image files.

stats.BoundingBox(3) would be equivalent to writing a comma-delimited list,

stats(1).BoundingBox(3), stats(2).BoundingBox(3), stats(3).BoundingBox(3)

and so on until the end of the array.

Using this definition, you can see that if stats only has a single member,
stats(1), that this would become just

stats(1).BoundingBox(3)

and thus stats.BoundingBox(3) would in that case be the same as
stats(1).BoundingBox(3)

Thank you for your comments.

You can find the code and the image being analysed at http://drop.io/jtcbpfb

I have also tried changing to stats.BoundingBox and removing the loop, however I get the following error when I do this:

??? Field reference for multiple structure elements that is followed by more
reference blocks is an error.

Error in ==> BlobsDemo_Anna3 at 106
keeperImage = find(([stats.Area] <= 8) & ([stats.BoundingBox(3)] <=10) &
([stats.BoundingBox(4)] <=10));

In that case,

arrayfun(@(v) v.BoundingBox(3), stats)

where you have stats.BoundingBox(3)

Thats works, thanks. However I am still having trouble filtering out the smaller areas from my code.
