Abstract: The bit stream from the set partitioning in hierarchical trees coder is divided into packets, which are protected by RCPT codes of different error-correcting capability before transmission according to their effect to the reconstruction of image. The genetic algorithms are developed for selecting optimal RCPT codes rates from the finite rates set in order to minimize the end-to-end distortion. The time for searching the optimal rate set is reduced when using the channel code rates for equal error protection as the initial condition of the genetic algorithms. Simulation results in binary symmetric channel show that this transmission scheme for progressive image is easy to perform and able to achieve high peak signal-to-noise ratio even in high bit error rate channel.
