| Research Abstract |
The purpose of this study was to classify perception states. Subjects were presented with binarization images and color images. The best classification accuracy was obtained when the beta band power was used as an input feature. Additionally, the conversion matrix of SVM was analyzed. As a result, the association of the memory was reflected in the alpha band activity in the parietal and parietal temporal region, thereafter, the contrast process comes into being in the beta band activity in the frontal region ; finally, the cognitive process accrues in the gamma band activity in the right occipital temporal region.
