Intra-frame Error Concealment for Multi-view Video with Hierarchical B Pictures Coding Structure
Three-dimensional video (3DV) will be the next step in the evolution of video services. Multi-view video using Hierarchical B Pictures (HBP) coding structure may be the main data format of 3DV. To address the problem of data packet loss during transmission of compressed multi-view video over wireless channel, we propose an intra-frame Error Concealment (EC) method for multi-view video with HBP structure. The concealment process is performed in three steps. First, we divide an intra-frame into background and foreground regions by utilizing the characteristic of short length of Group of Pictures (GOP) in multi-view video coding. Second, direct copy is applied to lost background blocks. Finally, adaptive orientation interpolation is used to conceal lost foreground blocks. The experimental results demonstrate that the proposed method outperforms the previous state-of-the-art intra-frame EC methods based on both subjective and objective measures, and decreases the effect of error propagation across view.
