A robust filtering methodology is proposed that reliably preserves the information encapsulated in a process signal corrupted with noise and outliers. The method is proven to be effective on benchmark examples and implemented successfully in real-tim

This paper addresses the detection of abnormal process situations during plant operation via an effective trending strategy. Wavelet-domain hidden Markov models (HMMs) are exploited as a powerful tool for statistical modeling and processing of wavele

The recovery of process information from noisy data de-noising is studied by investigating the classical solution of the estimation problem first. Next, the effectiveness of wavelet-based algorithms for data recovery is considered. A novel method bas
