The Application of Discrete Wavelet Transform with Improved Partial Least-Squares Method for the Estimation of Soil Properties with Visible and Near-Infrared Spectral Data

Remote Sensing, 2018
This study evaluated whether wavelet functions (Bior1.3, Bior2.4, Db4, Db8, Haar, Sym4, and Sym8) and decomposition levels (Levels 3–8) can estimate soil properties. The analysis is based on the discrete wavelet transform with partial least-squares

HAAR WAVELET ANALYSIS OF CLIMATIC TIME SERIES

International Journal of Wavelets, Multiresolution and Information Processing, 2014
In order to extract the intrinsic information of climatic time series from background red noise, in this paper, we will first give an analytic formula on the distribution of Haar wavelet power spectra of red noise in a rigorous statistical framework. After that, by comparing the difference of wavelet power spectra of real climatic time series and red ...

ABOUT MULTISCALE MODELING WITH THE USE OF HAAR DISCRETE WAVELETS FOR TARGETED DATA EXTRACTION IN PROBLEMS OF STRUCTURAL MECHANICS

International Journal for Computational Civil and Structural Engineering
The distinctive paper is devoted to multiscale modelling of functions with the use of Haar discrete wavelets. Numerical implementation is realized with the use of “Fortran” programming language (“Intel Visual Fortran” software).

Combined application of continuous wavelet transform-zero crossing technique in the simultaneous spectrophotometric determination of perindopril and indapamid in tablets

Química Nova, 2009
Signal processing methods based on the combined use of the continuous wavelet transform (CWT) and zero-crossing technique were applied to the simultaneous spectrophotometric determination of perindopril (PER) and indapamide (IND) in tablets. These signal

Comparative Study of Image Denoising Using Wavelet Transforms and Optimal Threshold and Neighbouring Window

مجلة كلية التربية للبنات, 2019
NeighShrink is an efficient image denoising algorithm based on the discrete wavelet transform (DWT). Its disadvantage is to use a suboptimal universal threshold and identical neighbouring window size in all wavelet subbands.
