Motion detection via image alignment

摘要: Pixels of an image are classified as being stationary or moving, based on the gradient in vicinity each pixel. The values corresponding pixels two sequential images compared. If difference between is less than about pixel location, a given threshold value above gradient, stationary. By classifying pixel, sensitivity motion detection classification reduced at edges objects, and other regions contrast image, thereby minimizing occurrences ghost artifacts caused by misclassification moving pixels.
