“…The DCT can preserve the image quality better than the wavelet transform, which can introduce artifacts and distortions due to its isotropic and homogeneous nature [ 24 ]. The DCT can also handle images with different orientations and scales better than the wavelet transform, which can lose information and resolution when dealing with anisotropic and heterogeneous images [ 26 ]. Alzubi [ 24 ] discussed how wavelet, ridgelet, and curvelet transforms can perform multi-resolution analysis for segmentation systems.…”

“…This affects the video imperceptibility and increases the transmission rate to some extent since many of coefficients are moved. In [9], Lin et al apply other reversible data hiding algorithm which bases on differential expansion (DE) to meet the goal of error resilient. Since four times of DE are required to embed pixel values into QDCT, computational complexity is higher.…”

Abstr act. For the purpose of improving the quality of wireless video transmission, this paper proposed an error resilience scheme based on reversible data hiding to reconstruct lost blocks. The motion vector of each macroblock (MB) in Intra-Frame is extracted first. Then as the important data of each MB, it is imperceptibly embedded into corresponding MB of the same frame using a reversible data hiding technique. If the embedded data for a corrupted MB is still available at the decoder side, the lost MB can be recovered using extracted important data. Otherwise, the lost MB can be recovered with a traditional error concealment method. Simulation results show that our method has higher PSNR than the reference methods in H.264/AVC.

“…If no error occurs, the quality of embedded video is worse than the original video. To solve this problem, a difference expansion algorithm was adopted as a reversible data embedding method in [18]. However, the computational complexity of this algorithm is higher.…”

With the rapid development of multimedia and communication technologies, video communication is becoming the main service in wireless communication networks. In order to improve the quality of H.264 video transmissions over error-prone wireless networks, a data embedding based content-aware error recovery approach is proposed in this paper. At the encoder, the important data of each macroblock (MB) of the H.264 intra-coded I frame is extracted adaptively based on scene change information and embedded into the real-time transport protocol (RTP) header of the next frame. At the decoder, if the important data for a corrupted MB can be correctly extracted, the extracted important data will be used for error recovery. Simulation results show that the proposed approach can achieve better error recovery results than existing approaches with similar or less amount of embedded data.
