Video coding focuses on reducing the data size of videos. Video stabilization targets at removing shaky camera motions. In this paper, we enable video coding for video stabilization by constructing the camera motions based on the motion vectors employed in the video coding. The existing stabilization methods rely heavily on image features for the recovery of camera motions. However, feature tracking...
Perceptual audio hashing has been applied in audio content identification, retrieval and indexing for its accuracy and perceptual robustness. Security issue becomes important when perceptual hashing is applied in audio content authentication. A key-dependent compressed domain perceptual audio hashing algorithm for audio content authentication is proposed. A randomization scheme controlled by a random...
A robust audio hashing algorithm for AAC audio is proposed in this paper. The robust hash is calculated from MDCT-coefficients which are derived by partial decoding of AAC bitstream. There is no complicated transformation in the proposed algorithm, therefore, it is of low computational complexity. The proposed method is highly robust to MDCT-based audio compression. Experimental results also show...
In this paper, a perceptual audio hashing method in compressed domain is proposed for content identification, in which MDCT coefficients as the intermediate decoding result are selected for perceptual feature extraction and hash generation. The perceptual feature extraction is based on psychoacoustic model and exhibits good discrimination ability for different audio contents but robustness against...
