A method for camera motion estimation resistant to foreground motion dominance

摘要

Camera motion estimation is required to obtain accurate global motion estimation (GME) for video applications. Thus, present invention describes a method for camera motion estimation by using an initial motion vector field which is obtained from smooth motion estimation unit and by using vector median filtering. In present invention the number of reduction stages according to initial motion vector field is determined and for each reduction stage, vector median filtering is applied to present reduction stage motion vector field.
