Parallel and reliable execution of a WDR algorithm in high speed networks

This paper presents an idea for a parallel version of the WDR (wavelet difference reduction) compression algorithm. An implementation of the idea is applied to the Nguyen-Chen-Walker's WDR codec and related analysis are demonstrated. The parallel WDR codec (PWDR) reaches up to 50 percent speedup compared to the original sequential implementation for some images. A reliable extension of the parallelized program and analyses of its performance have been presented.
