摘要: Visually evoked potential (VEP) is an electrical signal generated by the brain (Occipital Cortex) in response to a visual stimuli. These VEP are recorded non-invasively placing surface electrodes at scalp, and observed as reading on electroencephalogram (EEG). has been widely used for diagnostics of vision impairments patients. The main parameters that were considered these diseases amplitude latency values. This field study gaining interest from researches all over world. In this paper, time domain based features studied effort discriminate normal subjects those having impairments. Three different classifiers, Linear Discriminant Analysis (LDA), Quadratic (QDA) k Nearest Neighbor (kNN) investigation. proposed method shows promising results investigation with accuracy ranging 69.44% 100%.
