Abstract
A video image interference detection method includes the following steps: acquiring a background image and a current frame image; constructing an edge image of the background image and an edge image of the current frame image respectively; intersecting the edge image of the background image and the edge image of the current frame image to obtain a same boundary image between the edge image of the background image and the edge image of the current frame image; counting a first pixel number in the edge image of the background image and a second pixel number in the same edge image; determining whether the current frame image is interfered according to a ratio of the first pixel number to the second pixel number.
