Abstract
A method and system for estimating global motion in digital imaging applications with confidence level filtering. Motion search yields a plurality of vectors describing the movement of feature blocks from one frame to another. A confidence level is assigned to each motion vector. Based on the confidence levels, vectors are given more or less weight when estimating global motion. High-confidence vectors are given more weight than low-confidence vectors. Embodiments for estimating both the magnitude of global motion and the magnitude and direction of global motion are disclosed.
