Motion detector based on difference with predefined background frame.

The class implements motion detection algorithm, which is based on difference of current video frame with predefined background frame. The difference frame is thresholded and the amount of difference pixels is calculated. To suppress stand-alone noisy pixels erosion morphological operator may be applied, which is controlled by SuppressNoise property.

In the case if precise motion area's borders are required (for example, for further motion post processing), then KeepObjectsEdges property may be used to restore borders after noise suppression.

In the case if custom background frame is not specified by using SetBackgroundFrame(Bitmap) method, the algorithm takes first video frame as a background frame and calculates difference of further video frames with it.

Unlike TwoFramesDifferenceDetector motion detection algorithm, this algorithm allows to identify quite clearly all objects, which are not part of the background (scene) - most likely moving objects.

Sample usage:

// create motion detector MotionDetector detector = new MotionDetector( new CustomFrameDifferenceDetector( ), new MotionAreaHighlighting( ) ); // continuously feed video frames to motion detector while ( ... ) { // process new video frame and check motion level if ( detector.ProcessFrame( videoFrame ) > 0.02 ) { // ring alarm or do somethng else } }
