- W2158149659 abstract "Data lost in the form of dropped packets is a major obstacle to actualizing real time Internet video via modem connection with frame rates as high as 30 frames per second. Error concealment (EC) techniques must restore the lost data. Due to rigid system specifications of this application, only the computationally simplest error concealment methods are plausible. Replication, which is the simplest temporal error concealment (TEC) method, fits well in this situation. There are however circumstances when replication is inadequate and linear interpolation, the simplest spatial EC, is used in its place. In this work, we consider an alternative spatial EC to linear interpolation, i.e. the DCT-coefficient based EC algorithm, with comparable computational cost and consistently better image quality in real-time Internet video applications." @default.
