Selective Crypting with Haar-Wavelets
2000The coefficients of a wavelet—decomposition form into different levels according to the size of the described details. This can be utilized to crypt only a part of the given data while keeping the rest unchanged so that critical information is filtered out.

Haar Wavelets on Spherical Triangulations
2005We construct piecewise constant wavelets on spherical triangulations, which are orthogonal with respect to a scalar product on L2(\(\mathbb{S}\)2). Our classes of wavelets include certain wavelets obtained by Bonneau and by Nielson et al. We also prove the Riesz stability and show some numerical experiments.

Redundant Multiscale Haar Wavelet Transforms
2015We consider a redundant lifting scheme for Haar wavelet transform that does not use the polyphase decomposition. We also extend the method to a two-dimensional triangular lattice, and define a nonseparable two-dimensional redundant Haar wavelet transform on the lattice.
