Retrieves the last motion ratio.
Declaration
property MotionDetector_GlobalMotionRatio: Double read GetMotionDetector_GlobalMotionRatio;
__property double MotionDetector_GlobalMotionRatio=read=GetMotionDetector_GlobalMotionRatio
Function MotionDetector_CellMotionRatio(x As Long, y As Long) As Double
Description
Used to retrieve the last motion ratio (moved pixels count / total pixels count) of the grid's cells having their sensitivity enabled (value between 1 and 9).
The return value will be in the 0.0 to 1.0 range (e.g. 0.5775).
This value is the result of the motion detection of the last video frame received.
This value is also returned by the OnMotionDetected event.
