CHAPTER 2. FLAME DETECTION IN VISIBLE RANGE VIDEO 29Method-2.2 is successful in determining fire and does not recognize stationaryfire-colored objects such as the sun as fire. However, it gives false alarms when thefire-colored ordinary objects start to move, as in the case of a realistic scenario.An example of this is shown in Fig. 2.9 (a). The proposed method does not giveany false alarms for this case (Fig. 2.9 (b)). The fire-colored strip on the cargotruck triggers an alarm in Method-2.2 when the truck starts to move. Similarly,false alarms are issued with Method-2.2 in Movies 3, 7 and 9, although there areno fires taking place in these videos. The moving arm of a man is detected asfire in Movie 7 (Fig. 2.10 (c)), and a red parking car is marked as fire in Movie 9with Method-2.2 (Fig. 2.10 (d)).(a)(b)(c)(d)Figure 2.10: Sample images (a) and (b) are from Movies 7 and 9, respectively.(c) False alarms are issued for the arm of the man with the method using colorand temporal variation only (Method-2.2) [64] and (d) on the fire-colored parkingcar. Our method does not give any false alarms in such cases (see Table 2.2).Method-2.3 gives similar detection results for fire. However, it also suffers frominefficient analysis of the motion of fire colored objects. <strong>Fire</strong>-colored ordinary
