Classifying Motion Intention of Step Length and Synchronous Walking Speed by Functional Near-Infrared Spectroscopy

Figure 7

The feature vectors under the different levels of walking speed: (a) represents the feature vectors under the totalHb parameter; (b) represents the feature vectors under the difference between the oxyHb and deoxyHb parameters. The specific representation of serial numbers is shown in Table 3.
