In this paper, the Time-Frequency Image (TFI) of electroencephalogram (EEG) signals obtained from Time-Frequency Representation (TFR) is employed as a new method to analysis of focal EEG signals. Further, the gray image is sub-divided into frequency-bands known as rhythms of EEG signals. The image based features namely entropy, texture homogeneity (TH), inverse difference moment (IDM), power, and...
In this paper, an efficient technique for the analysis of Myopathy and normal electromyography (EMG) signals is proposed. Empirical mode decomposition (EMD) technique has been used to decompose non-stationary EMG signals in some set of narrow band intrinsic mode functions (IMFs). Hilbert transform of IMFs provides analytic signals, which are used for extraction of instantaneous frequency and instantaneous...
In this paper, a new method for automatic sleep stage classification based on time-frequency image (TFI) of electroencephalogram (EEG) signals is proposed. Automatic classification of sleep stages is an important part for diagnosis and treatment of sleep disorders. The smoothed pseudo Wigner–Ville distribution (SPWVD) based time-frequency representation (TFR) of EEG signal has been used to obtain...
