Pilot Study on Gait Classification Using fNIRS Signals

Figure 6

(a) The significant channels of three walking states under the total data. The red square represents digital 1: it means that the value of original seven matrices under this position has five or more under the top 30% proportion. The blue square represents digital −1: it means that the value of original seven matrices under this position has five or more under the bottom 30% proportion. The green square represents digital 0; it represents the all cases expert for above two. (b) The significant channels of three walking states under the difference between oxyHb and deoxyHb.
