Provided is a background recovering apparatus for deleting an object of an
arbitrary region and recovering a background covered with the object. The
apparatus includes a storing block for storing the input image sequence,
and storing the three dimensional (3D) position and posture information,
and focal length information; a geometric information extracting block
for extracting 3D with respect to the background; a background image
generating block for generating the background image; and a background
image inserting block for recovering the background by inserting the
background image into an arbitrary region of a first view point.
