Abstract |
Given a number of available layers of source data and a
transmission bit budget, we propose an algorithm that determines
how many layers should be sent and how many
protection bits should be allocated to each transmitted
layer such that the expected distortion at the receiver is
minimum. The algorithm is used for robust transmission
of progressively compressed 3D models over a packet
erasure channel. In contrast to the previous approach,
which uses exhaustive search, the time complexity of our
algorithm is linear in the transmission bit budget. |
