Figure 4From: Time-frequency optimization for discrimination between imagination of right and left hand movements based on two bipolar electroencephalography channelsMaps of the F score and of the value of Euclidean distance. This figure shows maps of the F score and of the value of Euclidean distance for the same subject in Figure 2. (A) F score of the time-frequency regions with 4-Hz wide frequency bands and 2-s wide time segments. The largest value is marked out by a small rectangle. (B) Euclidean distance of the time-frequency regions with 4-Hz wide frequency band and 2-s wide time segments. The largest value is marked out by a small rectangle.Back to article page
