Masked complex non-decimated wavelet features for patient-level classification of contrast-enhanced mammography
Sara Antonijevic, Brani Vidakovic
Contrast-enhanced spectral mammography (CESM) acquires two images of each breast, a low-energy image and a recombined contrast image, but two questions central to building a classi…
Quaternion Nondecimated Wavelet Descriptors for Multiclass Breast Histology Classification
Sara Antonijevic, Brani Vidakovic
Breast histology images carry diagnostic information in color, texture, orientation, and tissue architecture across a range of scales. In H&E microscopy this information is inheren…
Bayesian Inference for Incomplete 2x2 Diagnostic Tables
Sara Antonijevic, Danielle Sitalo, Brani Vidakovic
Incomplete reporting of diagnostic accuracy data remains a persistent problem in medical research. In many studies, only part of the 2x2 diagnostic table is reported, leaving denom…
Fluoride Varnish in a Changing Preventive Environment: A Reanalysis and Temporal Meta-Regression of Historical and Contemporary Trials
Sara Antonijevic, Danielle Sitalo, Brani Vidakovic
Historical trials of fluoride varnish reported large reductions in dental caries, but contemporary trials are often conducted against more intensive background prevention, so the i…
Wavelet Based Cross Correlations with Applications
Jack Kissell, Vijini Lakmini, Brani Vidakovic
Wavelet Transforms are a widely used technique for decomposing a signal into coefficient vectors that correspond to distinct frequency/scale bands while retaining time localization…
Ovarian Cancer Diagnostics using Wavelet Packet Scaling Descriptors
Raymond J. Hinton, Jihyun Byun, Dixon Vimalajeewa +1
Detecting early-stage ovarian cancer accurately and efficiently is crucial for timely treatment. Various methods for early diagnosis have been explored, including a focus on featur…
Non-decimated Quaternion Wavelet Spectral Tools with Applications
Taewoon Kong, Brani Vidakovic
Quaternion wavelets are redundant wavelet transforms generalizing complex-valued non-decimated wavelet transforms. In this paper we propose a matrix-formulation for non-decimated q…
Non-decimated Complex Wavelet Spectral Tools with Applications
Taewoon Kong, Brani Vidakovic
In this paper we propose spectral tools based on non-decimated complex wavelet transforms implemented by their matrix formulation. This non-decimated complex wavelet spectra utiliz…
Empirical Wavelet-based Estimation for Non-linear Additive Regression Models
German A. Schnaidt Grez, Brani Vidakovic
Additive regression models are actively researched in the statistical field because of their usefulness in the analysis of responses determined by non-linear relationships with mul…
An Empirical approach to Survival Density Estimation for randomly-censored data using Wavelets
German A. Schnaidt Grez, Brani Vidakovic
Density estimation is a classical problem in statistics and has received considerable attention when both the data has been fully observed and in the case of partially observed (ce…
WavmatND: A MATLAB Package for Non-Decimated Wavelet Transform and its Applications
Minkyoung Kang, Brani Vidakovic
A non-decimated wavelet transform (NDWT) is a popular version of wavelet transforms because of its many advantages in applications. The inherent redundancy of this transform proved…
