The lifting scheme offers a refined approach to implementing the Discrete Wavelet Transform (DWT) by decomposing traditional convolution-based filtering into a succession of simple, in-place ...

The Discrete Wavelet Transform (DWT) has gained the reputation of being a very effective signal analysis tool for many practical applications. This paper presents an approach towards VLSI ...

The experimental ultrasound data is always trained by measurement errors, internal and external noise. For this reason, it is always necessary to apply some signal processing operations, such as ...

A comprehensive time series analysis project featuring wavelet transforms, forecasting, anomaly detection, and interactive visualization. This project demonstrates state-of-the-art methods for ...

Wavelet-Enhanced PaDiM extends the PaDiM anomaly-detection framework by inserting a discrete wavelet transform (DWT) step before feature concatenation. Combining multi-layer CNN activations with ...

Abstract: The critical identification and subsequent therapeutic treatment of cardiac diseases requires a correct categorization of ECG signals. The presented feature of separating data is highly ...

Abstract: In scenarios where collaborators and non-collaborators coexist, it is important to enable covert information exchange among collaborators while evading detection. Based on isometric muscle ...
