IMPROVEMENT OF THE HYBRID FEATURE EXTRACTION METHOD FOR EMG SIGNALS

This study aims to discuss classification of 14 different finger movements from EMG signals by using new feature extraction technique. The detection/classification of finger movements consists of 3 main steps including, preprocessing, feature extraction and classification steps. In classification of EMG signals, the performance of the classifier directly depends on feature extraction methods, including, time, histogram and frequency-based methods. However, these feature extraction methods have several drawbacks including, high time complexity, high computation demand, user supplied parameters, etc. In this paper, a new feature extraction method has been proposed for the classification of finger movements from EMG signals to overcome these problems. The proposed method based on hybridization of 2-time domain feature extraction techniques. The use of this method resulted in an accuracy of 97.48% after 10-fold-cross-validation. The experimental results supported with statistical analysis show that proposed method is better than 9 feature extraction methods investigated in this pape
