The challenge in partial overlap images

Overlapping Subimages Can Happen Everywhere – Don’t Let It Be in Your Publication!

Here are 6 different sub-images. Can you spot where are the overlaps?

Overlapping microscopy images are a common image integrity issue in the life sciences publications. But why does it even happen?

Whether you are currently a senior editor, principal investigator, or a research student – you have probably experienced the endless hours of sitting behind the microscope, trying to capture the results of your latest experiment.

These captures will later become the published article’s figures – but could you tell if some of the captures were overlapping?

 

Microscopy images overlap usually happen as an honest mistake: working in different size scales, losing orientation and mixing up the microscope capture’s file names, can all lead to wrongly publishing two different microscopy subimages that partially overlap.

 

However, it can also be an unethical way of creating false results sometimes.

 

Nevertheless, as an editor or a PI, you would like to prevent it from being published and take the appropriate actions: for example, as a PI it might help you learn how it happened and explain to your lab team how to avoid future mistakes.

 

Detecting overlaps might be hard – even impossible sometimes. It requires the human eye to make multiplied comparisons, which most of us are not capable of doing.

 

Check yourself: were you able to detect the overlapping areas?

Beneath the page, you can find the answers, provided by the automated Proofig analysis.

Proofig results: Proofig compared instantly all the sub-images, and detected different sorts of manipulations & duplications, including overlapping.

Legend: Proofig flagging found 3 overlap duplications (marked with a red square). The blue lines represent the position of similar features within the images: lines intersection indicates that there was a rotation of the images. Images no. 1 & 2 are rotated in 180º, and no. 3 is rotated in 90º.
