Method for region tracking in an image sequence using a two-dimensional mesh |
摘要 |
A method for tracking a predetermined, two-dimensional portion of an image throughout a sequence of images, the method comprises the steps of selecting a reference frame; selecting the predetermined, two-dimensional portion within the reference frame by choosing a polygon that defines the boundary of the predetermined portion; fitting a reference mesh having at least three corner nodes and an inside node to the reference polygon; tracking the reference polygon in subsequent or previous image frames by tracking the corner nodes; mapping the reference mesh into the tracked polygon in the subsequent or previous image frames; and refining locations of the inside and corner nodes in the subsequent or previous image frames for tracking local and global motion of the predetermined portion.
