TT4D: Tensor‐Train‐based 4D Time‐Dependent Volume Rendering
Computer Graphics Forum, EarlyView.Abstract Visualizing large‐scale, time‐varying volumetric data using direct volume rendering remains a significant challenge in scientific visualization, particularly as data sizes and resolutions continue to increase. One promising direction for addressing this challenge is the use of tensor decompositions, which have proven to be a useful tool for ...

FlowGS: Controlling Information Flow for Graph‐Based Interaction in 3D Gaussian Splatting
Computer Graphics Forum, EarlyView.Abstract 3D Gaussian Splatting (3DGS) has recently enabled real‐time, high‐quality novel view synthesis. However, its formulation treats each Gaussian independently, lacking explicit information exchange between neighboring elements and limiting its ability to capture local structure.

BLAC-wavelets: a multiresolution analysis with non-nested spaces [PDF]
, 1993 . In the last five years, there has been numerous applications of wavelets and multiresolution analysis in many fields of computer graphics as different as geometric modelling, volume visualization or illumination modelling.

Geometric-textured bitree: transmission of a multiresolution terrain the Internet
Journal of Computer Science and Technology, 2002 Transmission of large terrain databases across the Internet is still worrying. A large terrain database requires a big number of polygons and textures, and that represents a problem with current bandwidth and resource limitations.

FaceMamba: Geometry‐Aware Mamba for Efficient Speech‐Driven 3D Facial Animation
Computer Graphics Forum, EarlyView.Abstract Speech‐driven 3D facial animation plays a pivotal role in immersive digital human applications. Recent works have explored Mamba‐based sequence modeling as an efficient alternative to Transformer, but they often suffer from limited cross‐modal alignment and insufficient control over fine‐grained facial deformations.

Discrete Wavelets and Multiresolution Analysis [PDF]
, 1993 Summary: In this paper we present an elementary discussion of the discrete wavelet transform. A major problem is formed by the construction of an orthonormal wavelet basis of the Hilbert space of square integrable functions. It is shown that the concept of a multiresolution analysis is very helpful to make such a construction.

Hilbert Transform Pairs of Wavelets
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT The orthogonal projection of a real orthonormal wavelet basis onto the Hardy space—consisting of functions whose Fourier transform is supported only on the positive real axis—yields a Parseval frame of wavelets. Motivated by practical considerations, Kingsbury proposed the use of two real scaling functions from multiresolution analyses (MRAs ...

Wavelet Multiresolution Analysis of High-Frequency FX Rates, Summer 1997 [PDF]
FX pricing processes are nonstationary and their frequency characteristics are time-dependent. Most do not conform to geometric Brownian motion, since they exhibit a scaling law with a Hurst exponent between zero and 0.5 and fractal dimensions between 1 ...

Comparison and Fusion of Multiresolution Features for Texture Classification
, 2004 In this paper, we investigate the texture classification problem with individual and combined multiresolution features, i.e., dyadic wavelet, wavelet frame, Gabor wavelet, and steerable pyramid. Support vector machines are used as classifiers.
