Background:

Epilepsy diagnosis commonly relies on electroencephalography (EEG), which records nonstationary brain signals.
Abnormal neural activity during seizures necessitates accurate feature extraction from EEG signals for detection.

Purpose of the Study:

To propose a novel morphological feature extraction technique for epilepsy detection using EEG signals.
To evaluate the efficacy of the proposed Local Binary Pattern (LBP) operator-based method for seizure identification.

Main Methods:

Utilized the Local Binary Pattern (LBP) operator to extract morphological features from EEG signals, capturing signal edges.
Calculated the sum of absolute differences of consecutive LBP values and interquartile range for signal variability and dispersion.
Employed a K-nearest neighbor classifier for classifying EEG data, tested on the CHB-MIT continuous EEG database.

Main Results:

Achieved a mean accuracy of 99.7% and mean specificity of 99.8% in epilepsy detection.
Demonstrated a low average false detection rate of 0.47/h and high sensitivity of 99.2% for 136 seizures.
The LBP-based feature extraction effectively identified discriminating patterns in EEG signals for epilepsy.

Conclusions:

The proposed LBP-based morphological feature extraction technique is highly effective for automated epilepsy detection from EEG.
This method offers a promising approach for improving the accuracy and reliability of seizure identification systems.
