Hi All,
RidgeRun has developed a gstreamer element that can be easily added to the gstreamer pipeline to detect when there is movement in a desired region of the frames given by the camera. The algorithm is agnostic of the camera and can be used in general with any sensor. If you want to take a look on it please check this video:
