Time frequency signal analysis and processing toolbox update 6.2: An enhanced research platform with new advanced high-resolution TFDs
الملخص
This paper describes the advancements, updates and improvements made in the new Time Frequency Signal Analysis TFSAP toolbox as compared with the previous TFSA toolbox version. The updates and improvements done in TFSA toolbox are in-line with the latest research done in recent few years in the field of time-frequency based signal analysis. TFSA Toolbox has proved in the past to be an efficient and popular tool for analyzing non-stationary signals. The new TFSAP Toolbox is an updated Matlab toolbox that extends the functionality of previous TFSA toolboxes. It provides additional options for generating new time-frequency distributions, and synthesizing a signal from its time-frequency distribution. It also includes options for analyzing real-life signals such as biomedical, speech and radar signals. Several demo scripts are also included in the new version to demonstrate the main functionality of the toolbox and to coach new users to use TFSA toolbox for advanced signal processing applications dealing with non-stationarities. The new version is renamed TFSAP 6.2; it can be downloaded for free as a service to the community.

Time-frequency signal and image processing of non-stationary signals with application to the classification of newborn EEG abnormalities
Boashash, Boualem; Boubchir, Larbi; Azemi, Ghasem ( IEEE , 2011 , Conference Paper)This paper presents an introduction to time-frequency (T-F) methods in signal processing, and a novel approach for EEG abnormalities detection and classification based on a combination of signal related features and image ... -
Estimating the number of components of a multicomponent nonstationary signal using the short-term time-frequency Rényi entropy
Sucic, Victor; Saulig, Nicoletta; Boashash, Boualem ( Springer , 2011 , Article)The time-frequency Rényi entropy provides a measure of complexity of a nonstationary multicomponent signal in the time-frequency plane. When the complexity of a signal corresponds to the number of its components, then this ... -
Instantaneous frequency based newborn EEG seizure characterisation
Mesbah M.; O'Toole J.M.; Colditz P.B.; Boashash B. (2012 , Article)The electroencephalogram (EEG), used to noninvasively monitor brain activity, remains the most reliable tool in the diagnosis of neonatal seizures. Due to their nonstationary and multi-component nature, newborn EEG seizures ...
