Abstract
A method of detecting a shot-cut in a sequence of video images on basis of a first set of segments (S1n-1, S2n-1, S3n-1 and S41-1) and a second set of segments (S1n, S2n, S3n and S4n) being determined by means of segmentation, comprises: creating a third set of segments (S1n, S2n-1, S3n-1 and S4n-1) on basis of the first set of segments (S1n-1, S2n-1, S3n-1 and S4n-1); computing a consistency measure C(n-1, n) on basis of a number of values representing overlap (A,ij) between respective pairs of segments, each pair off segments comprising one of the segments (Sjn-1) of the third set of segments and one of the segments (Sin) of the second set of segments; and comparing the consistency measure (C(n-1, n)) with a predetermined threshold (Tc,) and establishing that the shot-cut is detected if the consistency measure (C(n-1, n)) is below the predetermined threshold (Tc).
