Abstract Brain Computer Interface is an interesting and important research field that has
contributed widespread application systems. In the medical field, it is important for physically …

Given a two-dimensional smooth manifold M and a bijective projection p from M on a fixed
plane (or a subset of that plane), we explore systematically how a wavelet transform (WT) on …

We construct piecewise constant wavelets on spherical triangulations, which are orthogonal
with respect to a scalar product on L 2 (S 2). Our classes of wavelets include certain …

Two-dimensional wavelets are by now a standard tool in image processing, under the two
concurrent approaches, the Discrete Wavelet Transform DWT, based on the concept of …

We review the coherent state (or group-theoretical) construction of the continuous wavelet
transform (CWT) on the two-sphere. Next, we describe the construction of a CWT on the …

We survey the construction of the continuous wavelet transform (CWT) on the twosphere.
Then we discuss the discretization of the spherical CWT, obtaining various types of discrete …

Heterogeneous Correlation Modeling Based on the Wavelet Diagonal Assumption and on
the Diffusion Operator in: Monthly Weather Review Volume 137 Issue 9 (2009) Jump to …

We present a method for constructing wavelet bases on the unit sphere S 2 of R 3, using the
radial projection and an inner product associated to a convex polyhedron having the origin …

Starting from the one-dimensional Haar wavelets on the interval [0, 1], we construct
spherical Haar wavelets which are orthogonal with respect to a given scalar product. This …

The computation of sparse representations of data on the sphere (eg topographical data) is
a crucial step for further processing such as multiple separation, migration, imaging and …
