Researchers have introduced DeformView, a new dataset designed to help identify geometric inconsistencies in multi-view image sets, a problem that arises in novel view synthesis. Existing methods for evaluating novel view synthesis models do not effectively transfer to the task of localizing these geometric inconsistencies for multimedia forensics. To address this, a new lightweight classifier called DEFECt3R has been developed, which uses cross-view feature relationships to pinpoint geometric inconsistencies at the pixel level. Experiments show that DEFECt3R significantly improves localization performance and reduces false positives compared to prior methods. AI
