Since 20 15, Syracuse University in new york, USA, has been studying the algorithm of automatically extracting and identifying duplicate pictures from thousands of documents. This year, it has been successfully applied to identify pre-printed documents in COVID-19 (COVID 19). In this test, the research team * * * downloaded 3,500 papers with more than 20,000 pictures. In just 4 hours, the software found about 400 possible duplicate images, which can be said to be successful in small-scale experiments. This AI algorithm can screen and identify duplicate pictures, including those that have been flipped, rotated, scaled or even changed in contrast or color, and mark them. In other words, the pictures from P may still be found out.

It is a serious academic misconduct to reuse the pictures of articles and other articles. Publishing academic papers should not only be innovative, but also attract attention in academic ethics and scientific research integrity. Otherwise, as long as it is suspected of academic misconduct, even the published papers may be withdrawn.
