Fault Detection on Textiles by Adapted Biorthogonal Wavelets
In the discrete wavelet transform approach, a choice of wavelet has a direct impact on the decomposed image, which indicates that the selection of the wavelet is closely related to the detection performance. Since a choice ...

A Wavelet-Based T Wave End Detection: Prototype Wavelets Comparison
. Another conclusion is, that biorthogonal wavelets are less sensitive to a scale selection, so an algorithm based on a biorthogonal wavelet is more robust, than on a continuous wavelet transform. We used ...
