Claim 10:
11. The device according to claim 1, wherein the matching stage comprises a clean-up stage configured for receiving at least some of the partial matches detected by the detection stage and for determining a longest partial match of the partial matches, wherein the longest partial match of the received partial matches is a main diagonal of a rectangular portion of the similarity matrix, wherein a further partial match of the received partial matches, which extends at least partially into the rectangular portion of the similarity matrix is discarded, unless following conditions are met:
an absolute value of a horizontal distance between an earliest frame match of the longest received partial match and an earliest frame match of the further received partial match exceeds a distance threshold;
an absolute value of a vertical distance between the earliest frame match of the longest received partial match and the earliest frame match of the further received partial match exceeds the distance threshold;
an absolute value of a horizontal distance between a latest frame match of the longest received partial match and a latest frame match of the further received partial match exceeds a distance threshold;
an absolute value of a vertical distance between the latest frame match of the longest received partial match and the latest frame match of the further received partial match exceeds the distance threshold; and
a row index of the latest frame match of the further received partial match is greater than a row index of the latest frame match of the longest received partial match, in case that a column index of the latest frame match of the further received partial match is greater than a column index of the latest frame match of the longest received partial match,
wherein the not discarded partial matches are outputted.
