Orthogonality Conditions for Non-Dyadic Wavelet Analysis [PDF]

open access: yes
The conventional dyadic multiresolution analysis constructs a succession of frequency intervals in the form of ( π  / 2  j , π  / 2  j  - 1 ); j  = 1, 2, . . . ,  n of which the bandwidths are halved repeatedly in the descent from high frequencies to low

Automatic identification breast cancer using multiresolution algorithm

open access: yes, 2011
In this paper, we present a multiresolution scheme to detect stellate lesions in mammograms. Multiresolution analysis is used to analyze the images at different frequencies with different resolutions.

Multiresolution Analysis for Surfaces of Arbitrary Topological Type

open access: yes, 1994
Multiresolution analysis and wavelets provide useful and efficient tools for representing functions at multiple levels of detail. Wavelet representations have been used in a broad range of applications, including image compression, physical simulation ...

Wavelet Multiresolution Analysis of High-Frequency Asian FX Rates, Summer 1997 [PDF]

open access: yes
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 ...

From uncertainty to adaptivity : multiscale edge detection and image segmentation [PDF]

open access: yes
This thesis presents the research on two different tasks in computer vision: edge detection and image segmentation (including texture segmentation and motion field segmentation).
