      Xiao J; Tillo T; Zhang X (IEEE, 2011)
      How to compress a set of images in an efficient way is one of the most popular research topics. Currently, one of the most preferred standards for compressing still images is JPEG2000 which mainly utilizes Discrete Wavelet ...
    • Is burst loss worse than random loss for video transmission? 

      Xiao J; Tillo T; Lin C (IEEE, 2011)
      Many papers have shown that burst loss causes more severe damage to the reconstructed video quality than random loss for the same packet loss rate. With traditional interleaving methods, the consecutive lost packet positions ...
