)

static member CalcGlobalOrientation : 
        orientation : IInputArray * 
        mask : IInputArray * 
        mhi : IInputArray * 
        timestamp : float * 
        duration : float -> float 

Parameters

orientation

Type: Emgu.CVIInputArray
Motion gradient orientation image; calculated by the function cvCalcMotionGradient.

mask

Type: Emgu.CVIInputArray
Mask image. It may be a conjunction of valid gradient mask, obtained with cvCalcMotionGradient and mask of the region, whose direction needs to be calculated.

mhi

Type: Emgu.CVIInputArray
Motion history image.

timestamp

Type: SystemDouble
Current time in milliseconds or other units, it is better to store time passed to cvUpdateMotionHistory before and reuse it here, because running cvUpdateMotionHistory and cvCalcMotionGradient on large images may take some time.

duration

Type: SystemDouble
Maximal duration of motion track in milliseconds, the same as in cvUpdateMotionHistory
