Performance evaluation and optimization of embedded image sources over noisy channels

We investigate and prove the relationships among several commonly used and new performance metrics for embedded image bit streams transmitted over noisy channels. The average of the first error-free run length (FEFRL) is proposed as a simpler performance metric. On binary symmetric channels (BSC), the average FEFRL is obtained in closed form, which greatly simplifies performance optimization. Simulation results justify the merit of the proposed technique.
