Fundamental Frequency Extraction Method using Central Clipping and its Importance for the Classification of Emotional State

open access: yesAdvances in Electrical and Electronic Engineering, 2012
The paper deals with a classification of emotional state. We implemented a method for extracting the fundamental speech signal frequency by means of a central clipping and examined a correlation between emotional state and fundamental speech frequency ...

A Novel Deep-Learning-Based Framework for the Classification of Cardiac Arrhythmia

open access: yesJournal of Imaging, 2022
Cardiovascular diseases (CVDs) are the primary cause of death. Every year, many people die due to heart attacks. The electrocardiogram (ECG) signal plays a vital role in diagnosing CVDs. ECG signals provide us with information about the heartbeat.

Extraction of Features in EEG

open access: yesJournal of Robotics and Mechatronics, 1997
We take various information from the outside world into our brain by moving our eyes in every direction and sounds EEG contain basic rhythms of the brain, such as alpha waves, and components, such as myoelectric potentials. The results of the simulation indicated that the use of multiple windows would raise the accuracy in the detection of time delays ...

Stochastic Period and Cohort Effect State-Space Mortality Models Incorporating Demographic Factors via Probabilistic Robust Principal Components

open access: yesRisks, 2017
In this study we develop a multi-factor extension of the family of Lee-Carter stochastic mortality models. We build upon the time, period and cohort stochastic model structure to extend it to include exogenous observable demographic features that can be ...

Image Representation Using Stacked Colour Histogram

open access: yesAlgorithms, 2021
Image representation plays a vital role in the realisation of Content-Based Image Retrieval (CBIR) system. The representation is performed because pixel-by-pixel matching for image retrieval is impracticable as a result of the rigid nature of such an ...
