In order to establish a synergy between the compression scheme and the intended processing of the compressed image, we develop a family of compression algorithms that can adapt to the specialized requirements imposed by the application. The focus of this work is on wavelet-based compression for still images. A family of eight compression schemes is proposed to address specialized multimedia requirements such as (i) partial evaluation of wavelet coefficients, (ii) asymptotic losslessness of the algorithms, (iii) tree-structure in the selected coefficients, and (iv) optimization of either energy compaction or coefficient retention. Experimental results, including fraction of coefficients evaluated, rate-distortion performance, and coefficient retention are presented.
