Error resilient image coding for radio channels

This paper explores the application of the error resilient coding scheme, absolute addressed picture element coding (APEL), to progressive image transmission over narrow-band radio channels, such as HF. Picture element (pel) interleaving strategies are explored and APEL coding and its merits are discussed. Demonstrated through air-trial results, this novel image coding approach are shown to restrict error propagation through its unique coding structure and offer reconstructed images of increasing definition as transmissions progress.
