In lossy packet networks such as the Internet, information often gets lost due to, e.g., network congestion. While these problems are typically solved by Active Error Concealment techniques such as error correcting codes, they do not always work for …
In video communication over lossy packet networks (e.g., the Internet), packet loss errors can severely damage the transmitted video. The damaged video can largely be repaired with passive error concealment, where neighboring information is used to …
In image communication over lossy packet networks (e.g., cell phone communication), packet loss errors lead to damaged images. Damaged images can be repaired with passive error concealment methods, which use neighboring coefficient or pixel values to …
