CSM In Motion Vector Steganalysis: The Effect of Coders on Motion Vectors in H.264 Video Encoding
ICASSP 2023accepted
Cover-Source Mismatch (CSM) has long been recognized as a major challenge in machine-learning based image steganalysis. However, little is known about the impact of CSM on motion vector (MV) based video steganalysis. As CSM stemming from factors at the end of the processing pipeline is particularly…
