Investigation of Luminance Effect on the Emotional Assessment Using Hjorth Descriptors

Medical Technologies National Conference (TIPTEKNO) --OCT 27-29, 2016 -- Antalya, TURKEYWOS: 000455003600076The aim of this study is to investigate the impact of luminance level on the emotional evaluation from electroencephalography (EEG) records. EEG recordings obtained from 31 healty partipicants were used in this study. Featires were obtained from EEG recordings using short time fourier transform (STFT) and Hjorth descriptors. According to the performance evaluation results (accuracy percentage), the value of the attributes of 70.97% of partipicants obtained from EEG recordings using the ORIGINAL negative visual stimule to be greater than the values of the attributes obtained from EEG recordings using the BRIGHT negative visual stimule were found. This observation was observed in the O2 electrode spatially region and delta frequency. This study is the beginning research on this subject and it is considered the results of this study will shed light on the issue
