Selective motion estimation apparatus and method combining global motion estimation method and local motion estimation method (Local Motion Estimation)

摘要

The present invention provides a method and apparatus for selecting and estimating a motion estimation method that combines a global motion estimation method and a local motion estimation method so as to more accurately perform motion estimation by effectively combining a global motion estimation method and a local motion estimation method according to a motion estimation region .;A global motion estimation unit for performing global motion estimation on an input object receiving an object mask for an input image and an input image, an arbitrary region among global motion estimation regions divided using an input object mask A first local motion estimator for estimating motion of an object by applying a local motion estimation method to an output of the global motion estimator for an area selected by the local region selector, A second local motion estimator for estimating a motion of an object by applying an independent local motion estimation method to an object of the image, a region selection unit for selecting an area region selection unit, and a controller for controlling outputs of the first and second local motion estimation units .
