Pairwise Linear Discriminant Analysis of Electromyographic signals
Electromyographic (EMG) signals are used as rich information sources for control of intelligent prosthetics. For efficient classification the machine learning algorithms used should allow the nonlinear nature of the multi class problem. For generalized application they should have the analytical ability to systematically tackle the problem in hand. To meet these requirements a pair-wise Linear ...
متن کاملDecomposition and Analysis of Intramuscular Electromyographic Signals
The clinical community has long shown interest in the concept of extracting as many motor unit action potentials (MUAPs) as possible from an intramuscular electromyographic (EMG) signal. Adrian and Bronk (1929) developed the first concentric needle electrode to identify both shape and firing rate of the MUAPs. Subsequent manual approaches of graphically measuring and quantifying the EMG signal ...
متن کاملReal-Time Classification of Electromyographic Signals for Robotic Control
Advances in bioengineering have led to increasingly sophisticated prosthetic devices for amputees and paralyzed individuals. Control of such devices necessitates real-time classification of biosignals, e.g., electromyographic (EMG) signals recorded from intact muscles. In this paper, we show that a 4-degrees-of-freedom robotic arm can be controlled in real-time using non-invasive surface EMG si...
متن کاملDecomposition of multichannel electromyographic signals for a silent speech interface
Silent speech interfaces (SSI) provide ways capture silently spoken human speech. In electromyography (EMG) based SSIs, surface electrodes attached to the user’s face record electric signals, which are used to infer speech. It is an important goal to increase wearing comfort and decrease system setup time by reducing the number of devices attached to the user’s face. By using multi-electrode ar...
متن کاملPrincipal Component Analysis of Electromyographic Signals: An Overview
Surface electromyography (EMG) is a widely used, straight-forward, technique which allows to investigate patterns of neuromuscular activation. In contrast to the relative simplicity of the recording technique, the analysis of the derived electric signals may be rather sophisticated. The last decade, in particular, has been characterized by the development of a several quantitative approaches to...
