Combined Forward Error Control and Packetized Zerotree Wavelet Encoding
for Transmission of Images Over Varying Channels
Pamela Cosman, Jon Rogers, P. Greg Sherwood, and Kenneth Zeger
Abstract
One method of transmitting wavelet based zerotree encoded images over
noisy channels is to add channel coding without altering the source
coder. A second method is to reorder the embedded zerotree bitstream
into packets containing a small set of wavelet coefficient trees.
We consider a hybrid mixture of these two approaches and
demonstrate situations in which the hybrid image coder can
outperform either of the two building block methods, namely on
channels that can suffer packet losses as well as
statistically varying bit errors.
