Method and Apparatus for Detecting Foregroud Image with Separating Foregroud and Background in Image

摘要

A method and apparatus for detecting a foreground image by separating a foreground and a background of an image are disclosed. An apparatus for detecting a foreground image by separating a foreground and a background of a captured image, the apparatus comprising: an image acquisition unit obtaining an image frame of the captured image; A block setting unit configured to set the image frame to a pixel block including two or more pixels; An input pixel determiner configured to determine any one of pixels included in the pixel block as an input pixel; A background model processor configured to acquire a main background model corresponding to the image frame, and update a background model corresponding to the input pixel among the main background models to generate a new background model; A foreground pixel detector detecting a foreground pixel based on a difference value calculated by comparing the input pixel with the latest background model; And a foreground image generating unit generating the foreground image corresponding to the moving object in the image frame based on the foreground pixel.
