1. An apparatus, comprising: a comparator configured to identify features of a first image, and features of a second image that match the features of the first image, wherein the features of the second image that match the features of the first image define a set of matched features; a stabilizer configured to generate stabilized frames through motion model estimation based on inlier features having passed a zone-of-interest test that confirms that the inlier features are distributed over a plurality of zones across the first and second images; and an outlier remover configured: to identify as an outlier feature any outlying feature of the first and second images identified by the comparator; to identify as an inlier feature any other feature of the first and second images identified by the comparator; and to provide the inlier features to the stabilizer.
