Application of Model-Based Estimation to Time-Delay Estimation of Ultrasonic Testing Signals
Time-Delay-Estimation (TDE) has been a topic of interest in many applications in the past few decades. The emphasis of this work is on the application of model-based estimation (MBE) for TDE of ultrasonic signals used in ultrasonic thickness gaging. Ultrasonic thickness gaging is based on precise measurement of the time difference between successive echoes which reflect back from the back wall ...
متن کاملDetection of Clicks in Audio Signals Using Warped Linear Prediction
In this work warped linear prediction (WLP) is applied to a model-based method to detect impulsive disturbances in audio signals. According to simulations performed on artificially corrupted audio signals the adoption of negative values for the warping factor favors the click detection scheme. As a consequence, for equal levels of missing (false) detection the WLP-based scheme yields consistent...
متن کاملWarped-Linear Models for Time Series Classification
This article proposes and studies warped-linear models for time series classification. The proposed models are time-warp invariant analogues of linear models. Their construction is in line with time series averaging and extensions of k-means and learning vector quantization to dynamic time warping (DTW) spaces. The main theoretical result is that warped-linear models correspond to polyhedral cl...
متن کاملAlternatives for Warped Linear Predictors
Linear Prediction (LP) is a well-known compression tool for coding speech and audio signals. By employing a frequency-warping technique, an extension has been proposed called Warped Linear Prediction (WLP). WLP enables controlling the degree at which details in specific regions in the spectral envelope can be conserved. Therefore, the coder can be tuned to a particular application. However, the...
متن کاملAn experimental audio codec based on warped linear prediction of complex valued signals
Bark-scale warped linear prediction [WLP] is a very potential core for a monophonic perceptual audio codec [2]. In the current paper the WLP scheme is extended for processing complex valued signals (CWLP). Three di erent methods of converting a stereo signal to one complex valued signal are introduced. The philosophy behind the coding scheme is to integrate some aspects of modern wideband audio...
