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)
Recently, the modernization of traditional Chinese medicines (TCM) for treatment of patients with critical and/or life-threatening diseases has attracted much attention in the pharmaceutical industry. However, there exist essential differences in the evaluation of the efficacy and safety of a TCM as compared with a typical Western medicine (WM), even though(More)
OBJECTIVES To explore the relationships between traditional Chinese medicine (TCM) syndromes and disease severity and prognoses after ischemic stroke, such as neurologic deficits and decline in activities of daily living (ADLs). METHODS The study included 211 patients who met the inclusion criteria of acute ischemic stroke based on clinical(More)
In this paper, we propose a universal reversible data hiding method for arbitrary red-green-blue (RGB) color filter array (CFA) captured mosaic images. Based on spectral-spatial correlation, a new universal prediction scheme, which automatically calculates the predicted values in the color difference domain according to the corresponding mosaic structure,(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)
