How to identify bubbles

  • lpmoura by lpmoura

    I'm not sure I'm doing it right.

    Not sure what a bubble bubble. I see many in this image.
    Could anyone explain the difference for me, please?

    BTW I saw the 5 examples at the Classifier's Guide. Couldn't be sure enough

    I wouldn't mark those as bubbles, since they are faint and do not have very defined edges.

    Yes -- bubbles tend to have defined edges.
    This image is very zoomed in, and its possible that these are just background fluctuations in the image or very very faint gas clouds.
