||Model-based real-time progressive transmission of images over noisy channels
||Many unequal error protection algorithms used in
image communication systems need the operational distortion-rate
(D/R) curve of the source coder whose computation is timeconsuming.
We study the use of parametric models instead of the true
D/R curves for wavelet-based embedded image and video coders. We
propose a Weibull model and show its superiority to the previous
models for real-time applications. For unequal error protection over
binary symmetric and packet erasure channels, the Weibull model
yielded performance similar to the one obtained with the true D/R
curve while satisfying the real-time constraint.
