Currently, two error propagation-free discrete cosine transform (DCT)-based data hiding algorithms, one by Ma et al. and the other by Lin et al., were presented for H.264/AVC intra-coded frames. However, the state-of-the-art video codec, high efficiency video coding (HEVC), adopts both integer DCT and discrete sine transform (DST) such that the previous(More)
—Efficient data hiding algorithms have been developed for video coders such as MPEG-4 and H.264/AVC, to deliver embedded information. Lin et al. proposed an error propagation free discrete cosine transform (DCT) based data hiding algorithm in H.264/AVC intra-coded frames. However, the state-of-the-art video codec, high efficiency video coding (HEVC), adopts(More)
