Abstract
A moving object detection method and apparatus are disclosed. The method may include: obtaining a first image and a second image of a scene; determining a difference of the first image and the second image; performing a binarization operation on the difference of the first image and the second image, to generate a binary image; determining the number of pixels whose values are nonzero in each column of the binary image, to generate a column pixel histogram; and determining whether a moving object is present in the scene based on the column pixel histogram.
