Using Discrete Wavelet Transform to Model Whistle Contours for Dolphin Species Classification

open access: yesProceedings, 2018
This work proposes the use of features based on the discrete wavelet transform (DWT) for dolphin species classification. These features are compared with other previously used in the literature, and the experiments carried out in a database featuring ...

Human Face Recognition Using Wavelet Network

open access: yesAl-Khawarizmi Engineering Journal, 2017
This paper presents a study of wavelet self-organizing maps (WSOM) for face recognition. The WSOM is a feed forward network that estimates optimized wavelet based for the discrete wavelet transform (DWT) on the basis of the distribution of the input data,

Leg Motion Classification with Artificial Neural Networks Using Wavelet-Based Features of Gyroscope Signals

open access: yesSensors, 2011
We extract the informative features of gyroscope signals using the discrete wavelet transform (DWT) decomposition and provide them as input to multi-layer feed-forward artificial neural networks (ANNs) for leg motion classification.

A fast discrete wavelet transform algorithm for visual processing applications

open access: yes, 2013
For visual processing applications, the two-dimensional (2-D) Discrete Wavelet Transform (DWT) can be used to decompose an image into four-subband images.

Detection and removal of “smacking” artefacts from lector speech records

open access: yesArchives of Acoustics, 2014
In the paper, analysis of “smacking” artefacts, introduced to the speech signal by a lector, was shown. A working algorithm to reduce amount of smacks in the waveform was presented.
