            Motion detector based on simple background modeling.
            </summary>
            
            <remarks><para>The class implements motion detection algorithm, which is based on
            difference of current video frame with modeled background frame.
            The <see cref="P:AForge.Vision.Motion.SimpleBackgroundModelingDetector.MotionFrame">difference frame</see> is thresholded and the
            <see cref="P:AForge.Vision.Motion.SimpleBackgroundModelingDetector.MotionLevel">amount of difference pixels</see> is calculated.
            To suppress stand-alone noisy pixels erosion morphological operator may be applied, which
            is controlled by <see cref="P:AForge.Vision.Motion.SimpleBackgroundModelingDetector.SuppressNoise"/> property.</para>
            
            <para><note>In the case if precise motion area's borders are required (for example,
            for further motion post processing), then <see cref="P:AForge.Vision.Motion.SimpleBackgroundModelingDetector.KeepObjectsEdges"/> property
            may be used to restore borders after noise suppression.</note></para>
            
            <para>As the first approximation of background frame, the first frame of video stream is taken.
            During further video processing the background frame is constantly updated, so it
            changes in the direction to decrease difference with current video frame (the background
            frame is moved towards current frame). See <see cref="P:AForge.Vision.Motion.SimpleBackgroundModelingDetector.FramesPerBackgroundUpdate"/>
            <see cref="P:AForge.Vision.Motion.SimpleBackgroundModelingDetector.MillisecondsPerBackgroundUpdate"/> properties, which control the rate of
            background frame update.</para>
            
            <para>Unlike <see cref="T:AForge.Vision.Motion.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. And unlike <see cref="T:AForge.Vision.Motion.CustomFrameDifferenceDetector"/> motion
            detection algorithm, this algorithm includes background adaptation feature, which allows it
            to update its modeled background frame in order to take scene changes into account.</para>
            
            <para><note>Because of the adaptation feature of the algorithm, it may adopt
            to background changes, what <see cref="T:AForge.Vision.Motion.CustomFrameDifferenceDetector"/> algorithm can not do.
            However, if moving object stays on the scene for a while (so algorithm adopts to it and does
            not treat it as a new moving object any more) and then starts to move again, the algorithm may
            find two moving objects - the true one, which is really moving, and the false one, which does not (the
            place, where the object stayed for a while).</note></para>
            
            <para><note>The algorithm is not applicable to such cases, when moving object resides
            in camera's view most of the time (laptops camera monitoring a person sitting in front of it,
            for example). The algorithm is mostly supposed for cases, when camera monitors some sort
            of static scene, where moving objects appear from time to time - street, road, corridor, etc.

            frame will be update for 3 intensity levels in the direction to decrease difference
