Unlike standard wavelet techniques, a multiple multiresolution analysis (MMRA) makes use of filterbanks based on level-varying scaling matrices and low-pass/high-pass filters chosen from finite given sets. This approach allows for a better detection of directional singularities in images, especially when sets of anisotropic scaling matrices are employed. We present a general construction of orthogonal MMRAs and examples of their application to some image processing problems specifically requiring compression and detection capabilities of the processing system.
