In this article, we aim to detect the double compression of MPEG-4, a
universal video codec that is built into surveillance systems and shooting
devices. Double compression is accompanied by various types of video
manipulation, and its traces can be exploited to determine whether a video is a
forgery. To this end, we present a neural network-based approach with
discriminant features for capturing peculiar artifacts in the discrete cosine
transform (DCT) domain caused by double MPEG-4 compression. By analyzing the …
