Lossy to lossless image compression using allpass filters
In this paper, an effective implementation of the allpass-based orthonormal symmetric wavelets is proposed for image compression. Since the orthonormal symmetric wavelets are used...

Lossless/lossy coding gain to evaluate coding performance of the lossless/lossy wavelet
In this report, we propose lossless/lossy coding gain as a new objective criterion to theoretically evaluate lossless and lossy coding performance of the lossless/lossy wavelet (L...
