Abstract

An object detection method and an apparatus thereof are provided. In the object detection method, a plurality of images in an image sequence is sequentially received. When a current image is received, a latest background image is established by referring to the current image and the M images previous to the current image, so as to update one of N background images, wherein M and N are positive integers. Next, color models of the current image and the background images are analyzed to determine whether a pixel in the current image belongs to a foreground object. Accordingly, the accuracy in object detection is increased by instantly updating the background images.
