An optimal polygonal boundary encoding scheme in the rate distortion sense
—In this paper, we present fast and efficient methods for the lossy encoding of object boundaries that are given as eight-connect chain codes. We approximate the boundary by a p...

On statistical multiplexing of variable-bit-rate video streams in mobile systems
We consider the problem of broadcasting multiple variable-bit-rate (VBR) video streams from a base station to many mobile devices over a wireless network, so that: (i) perceived q...
