Imagetwin and Proofig AI are software tools that help scientists detect manipulated or copied images in research papers. These tools automate the process of image analysis, which used to be done manually by researchers. Imagetwin, in particular, compares images in a paper to a database of 51 million images, flagging any similarities or copies. The software has been successful in identifying problematic images and has been praised by researchers. However, it is not perfect and can sometimes miss certain issues. These tools offer a chance to improve the quality of published science and have already had an impact on the rejection rates of papers in some journals. However, there are concerns about the potential for AI algorithms to fabricate both text and images in scientific studies. [Extracted from the article]
