Tight Wavelet Filter Banks with Prescribed Directions
Youngmi Hur
Constructing tight wavelet filter banks with prescribed directions is challenging. This paper presents a systematic method for designing a tight wavelet filter bank, given any pres…
Deep Scattering Network with Max-pooling
Taekyung Ki, Youngmi Hur
Scattering network is a convolutional network, consisting of cascading convolutions using pre-defined wavelets followed by the modulus operator. Since its introduction in 2012, the…
Prime Coset Sum: A Systematic Method for Designing Multi-D Wavelet Filter Banks with Fast Algorithms
Youngmi Hur, Fang Zheng
As constructing multi-D wavelets remains a challenging problem, we propose a new method called prime coset sum to construct multi-D wavelets. Our method provides a systematic way t…
Committee Algorithm: An Easy Way to Construct Wavelet Filter Banks
Youngmi Hur
Given a lowpass filter, finding a dual lowpass filter is an essential step in constructing non-redundant wavelet filter banks. Obtaining dual lowpass filters is not an easy task. I…
Coset Sum: an alternative to the tensor product in wavelet construction
Youngmi Hur, Fang Zheng
A multivariate biorthogonal wavelet system can be obtained from a pair of multivariate biorthogonal refinement masks in Multiresolution Analysis setup. Some multivariate refinement…
