Abstract
A method and a device for checking the plausibility of a flow vector hypothesis includes ascertaining a prediction vector associated with a feature based on a movement of the feature between a first image and a second image that follows the first image in a sequence; generating a hypothesis vector that is associated with the feature and describes a presumed movement of the feature between the second image and a third image that follows the second image in the sequence; calculating a degree of similarity between the prediction vector and the hypothesis vector; and evaluating, based on the calculated degree of similarity, a plausibility of the hypothesis vector describing an actual movement of the feature between the second and third images.
