To circumvent the lack of knowledge of what measure is more suitable for optimization of the trade-off between image fidelity and coding rate, this paper shall introduce a novel mathematical methodology for rate control by organizing the progressive transmission in accordance with coherence constraints for avoiding forms of behavioral inconsistency. This methodology could be used within a progr...

A new image sharing method, based on the reversible integer-to-integer (ITI) wavelet transform and Shamir’s (r,m) threshold scheme is presented, that provides highly compact shadows for real-time progressive transmission. This method, working in the wavelet domain, processes the transform coefficients in each subband, divides each of the resulting combination coefficients into m shadows, and al...

This paper presents an optimal rate allocation scheme in joint sourcechannel coding (JSCC) for image transmission over CDMA networks. Our scheme first uses progressive joint source-channel codes [1] to generate operational transmission rate-distortion (TRD) functions of different multiple-access channels with different BERs. The Lagrange multiplier is then employed to set the optimal rate alloc...
