Abstract
Systems and methods for tracking the foreground and background objects in a video image sequence. The systems and methods providing for determining a camera model based on a first group of feature points extracted from a video frame, extracting three-dimensional (3D) information for the first group of feature points based on the camera model and a previous camera model for a previous video frame, reassigning feature points to the first group or a second group, based on mapping each feature point to a corresponding 3D model using the extracted 3D information for each feature point and determining a new camera model when a number of reassigned feature points is greater than a predetermined threshold.
