Nikon disqualifies microscopy winner over AI use
Nikon Instruments has disqualified the winning entry of its Small World in Motion microscopy competition after determining that the video violated rules prohibiting AI-generated content. The entry, submitted by optical engineer Ning Xu, depicted the movement of cilia in the lungs and was initially awarded first place on 15 September. However, scientists quickly raised concerns on LinkedIn,…
Key points
- Nikon disqualified the Small World in Motion winner because AI-generated videos are not permitted under competition rules.
- Ning Xu admitted using an AI model for post-processing to enhance visual presentation without making anatomical claims.
- Nikon stated the disqualification was based on rule compliance, not a judgment of the entrant's professional reputation or intent.
In response to the criticism, Xu stated that his team used an AI model during post-processing to enhance the visual presentation of areas below the cilia, clarifying that they made no anatomical claims about those rendered features. Nikon confirmed it had been investigating the submission since 25 September. After re-evaluating the video and consulting the judging panel, the company ruled that the entry did not comply with competition rules. Nikon emphasized that this decision was based solely on eligibility and should not be interpreted as a judgment on Xu’s professional reputation or intent. Xu did not respond to requests for comment, while the National University of Singapore noted that Xu participated in the competition before joining the university and that the submission was unrelated to his work there.
