Table 8 Comparing fusion ensembles consisting of all 5, 4 (DBIOSIGNaive, DBIOSIGMC, DarXivNaive, and DarXivMC), and 3 (DarXivNaive, DBIOSIGMC, Dkeypoints) detectors with the adaptive decision thresholds and fusion weights based on the estimated EER with the combined LondonDB/UtrechtDB/Alabama datasets (best result per morph type and ensemble size marked in bold)

From: Potential advantages and limitations of using information fusion in media forensics—a discussion on the example of detecting face morphing attacks
