“…Average optical flows of six regions located among these ten points are calculated. These six regions are bounded among the following points: a) 1,3,5,7 b) 2,4,5,7 c) 3,6,7 d) 4,6,7 e) 3,6,8,10 f) 4,6,910 These areas which can be seen in Figure 2 part (a) are chosen due to the fact that each of them has a different movement compared to the other parts while speaking. And it was expected that the optical flow vector illustrates the correct direction in each of them.…”
