But the fact remains that its American stronghold is not displaying the indefatigable stamina shown by Avatar; overseas, this weekend's take is already under $100m, a figure the Cameron film exceeded for six consecutive frames.
Features were considered lost in case of no match for five consecutive frames.
A target must be detected for three consecutive frames after its first appearance, and then for two out of three consecutive frames (after the first three consecutive frames) in order to be confirmed.
To avoid erroneous decisions caused by unexpected outliers in the sensor data, the delivery is started when the calculated occurrence probability (p y=1|varvec{x})) exceeds the threshold (p_T) for three consecutive frames.
By using color information from the eyeball, the state of the eye is defined; thus the driver's state can be computed, that is, asleep or alert; if the eyes are closed for five consecutive frames, the driver is assumed to be dozing.
In order to decrease the effects of these peaks and valleys, we have used an overestimation parameter by modifying the ANS equation to Fig. 5 Autocorrelation sequences for five consecutive frames of factory noise {r}_{mathrm{yy}}left( m, kright)={r}_{mathrm{xx}}left( m, kright)+alpha.{widehat{r}}_{mathrm{vv}} k), (29 where α ≥ 1 is the overestimation parameter.
After locating the eyes, it computes the fatigue index using the distance of the eyelid to classify whether the eyes are open or closed; if the eyes are closed for five consecutive frames, the driver is considering to be dozing, as in Horng's work.
As in the works of Horng et al. [12] and Dong and Wu [3], if for five consecutive frames or during 0.25 seconds the eye is identified as being closed the system issues an alarm cue, PERCLOS [7], which is also implemented in this system.
Movement onset was defined as the first frame that exceeded 50 mm/s for ten consecutive frames (50 ms) and movement offset was the first frame falling below 50 mm/s for ten consecutive frames.
