Wavelet geographically weighted regression for spectroscopic modelling of soil properties
Scientific Reports, 2021 Soil properties, such as organic carbon, pH and clay content, are critical indicators of ecosystem function. Visible–near infrared (vis–NIR) reflectance spectroscopy has been widely used to cost-efficiently estimate such soil properties.

Optimal multiple description and multiresolution scalar quantizer design [PDF]
, 2008 The author presents new algorithms for fixed-rate multiple description and multiresolution scalar quantizer design. The algorithms both run in time polynomial in the size of the source alphabet and guarantee globally optimal solutions.

Multiresolution analysis for irregular meshes [PDF]
SPIE Proceedings, 2004 The concept of multiresolution analysis applied to irregular meshes has become more and more important. Previous contributions proposed a variety of methods using simplification and/or subdivision algorithms to build a mesh pyramid. In this paper, we propose a multiresolution analysis framework for irregular meshes with attributes.

Quadratic Phase Multiresolution Analysis and the Construction of Orthonormal Wavelets in L2(ℝ)
Axioms, 2023 The multi-resolution analysis (MRA) associated with quadratic phase Fourier transform (QPFT) serves as a tool to construct orthogonal bases of the L2(R). Consequently, it assumes a pivotal role in facilitating potential applications of QPFT.

Multiresolution analysis applied to interpretation of seismic reflection data [PDF]
Geofísica Internacional, 2005 We have developed a method of seismic multiresolution analysis based on the discrete wavelet transform. We illustrate the potential use in petroleum exploration of the joint application of multiresolution analysis and seismic attributes for a real case ...

Analysis on Multiresolution Mosaic Images [PDF]
IEEE Transactions on Image Processing, 2004 Image mosaicing is the act of combining two or more images and is used in many applications in computer vision, image processing, and computer graphics. It aims to combine images such that no obstructive boundaries exist around overlapped regions and to create a mosaic image that exhibits as little distortion as possible from the original images.
