Recent Developments on Dual Wavelet Frames
We discuss some recent developments on pairs of dual wavelet frames in Sobolev spaces constructed by the Oblique Extension Principle (OEP) from refinable function vectors. Our investigation sheds a new light on understanding the OEP method for constructing MRA (multiresolution analysis) dual wavelet frames.
