Claim:
1. A method for stabilizing a first sequence of digital image frames comprising: determining a dominant motion vector of a dominant motion layer of said first sequence; determining a first part of the dominant motion vector representative of an intended motion in said first sequence; determining a second part of the dominant motion vector representative of an unintended motion in said first sequence; generating a second sequence from the first sequence based on the second part, the dominant motion vector being determined based on a weighted combination of all vectors that constitute the dominant motion layer; refining a current estimate of the dominant motion layer by weighting out motion vectors that are beyond a predetermined distance from the dominant motion vector, the dominant motion layer being represented as a matrix including values between a first value and a second value, the first value in the matrix indicating an outlier, and the second value in the matrix indicating an inlier; setting a third value in the matrix to the first value when the third value is below a first predetermined threshold; and setting a fourth value in the matrix to the second value when the fourth value is above a second predetermined threshold.
