The problem is viewed from a source coding perspective, where the main constraints are maximum coding efficiency and minimum redundancy. Error-resilient mechanisms are incorporated into wavelet-based image encoding schemes to obtain robust data streams that withstand significant bit errors and packet losses. The robust encoder requires no additional redundancy and shows coding improvements of 0.5-1.5 dB in SNR values over other similar methods. Redundant sets of wavelet coefficients generated by overcomplete discrete wavelet transform are used as side information to improve error-resilience at high packet loss rates. The implementations are flexible and can be easily adapted to any type of transmission channel with different network parameters.application/pdfengError resilienceImage transmissionImage codingDissertation
