Motion ratio
Motion detection and motion ratio.
Description
Motion ratio
The motion ratio is the result of motion detection between 2 video frames. All motion ratios values are within the 0..1 range.
For each video frame received:
a) if motion is detected:
The OnMotionDetected event occurs. This event returns the and returns a global motion ratio. From this event you can also query cells using CellMotionRatio (x, y) to get their individual motion ratio.
b) if no motion is detected:
The OnMotionNotDetected event occurs.
