Background subtraction (BS) is one of the most commonly encountered tasks in video analysis and tracking systems. It distinguishes the foreground (moving objects) from the video sequences captured by static imaging sensors. Background subtraction in

In order to eliminate the large amount of waste rock and tailings deposited on the surface, waste rock tailings are used as aggregate to prepare wet shotcrete, and fly ash is added instead of cement to reduce the cost. Based on the orthogonal test sy
