چکیده مقاله:
Visual information such as orientation, colour, and shape of the objects are analyzed separately in the primary visualcortex of the mammalian brain. The purpose of this project is to classify the signals taken through the EEG by fourdifferent orientation stimuli (horizontal, vertical, and ± 45 degrees). The number of subjects in this experiment was six,which according to the secondary studies on the signals, the data of the four subjects were selected. After the removal ofthe eyelid movement and muscle effects, signals are entered into the feature extraction and classification step. Thecomparison of ERP signals for each subject in each of the four oirentation shows an interesting result. The results ofthese analyzes indicate that, after viewing the images, a stimulation is observed in the signals, which are placed on thefour orientation with a slight difference in the attitude of the signals. These results can be attention effect in the subject.After the appearance of the attention peak, some time intervals can distinguish different orientations from each other.
