Lossless coding of multichannel signals using optimal vector hierarchical decomposition
Dimitrios K. Tzovaras, Michael Gerassimos Strintzis · IEEE Transactions on Image Processing · 2000
A methodology is presented for the optimal construction of multichannel reduced pyramids by selecting the interpolation synthesis postfilters so as to minimize the error variance at each level of the pyramid. The general optimization methodology is applied for the optimization of pyramids for the compression of electrocardiographic signals and RGB colored images.
