In previous work, we introduced a new image representation for the field of wavelet coefficients (dubbed MRWD), based on morphological operators. This work extends the MRWD framework, by addressing the effective design of image coding algorithms. First, we design an encoder with the goal of being optimal in the operational rate-distortion sense. Second, based on the same (morphological) techniques, we design a successively refinable version of the single rate coder. Simulation results are reported.
