Improved interview video error concealment on whole frame packet loss

• Proposed multiview error concealment method is 5.53 dB better than latest method.
• Optimal reference view selection for DIBR (Depth image based rendering) is proposed.
• The 1-to-1 pixels are chosen, and the light compensation is estimated correctly.
• The many-to-1 pixels are better estimated with the aid of depth information.
• Hole pixels are improved efficiently with the neighboring available motion vectors.

An improved DIBR-based (Depth image based rendering) whole frame error concealment method for multiview video with depth is designed. An optimal reference view selection is first proposed. The paper further includes three modified parts for the DIBRed pixels. First, the missing 1-to-1 pixels are concealed by the pixels from another view. The light differences between views are taken care of by the information of the motion vector of the projected coordination and a reverse DIBR procedure. Second, the generation of the many-to-1 pixels is improved via their depth information. Third, the hole pixels are found using the estimated motion vectors derived efficiently from a weighted function of the neighboring available motion vectors and their distance to the target hole pixel. The experimental results show that, compared to the state-of-the-art method, the combined system of the four proposed methods is superior and improves the performance by 5.53 dB at maximum.
