Patent ID: 7990477

Claim:
A method for detecting transitions in a video sequence, the method comprising detecting an abrupt transition including the following steps, for each image I t−2k included in said video sequence and with a processing time rank t−2k: calculation of a first distance D(I t−k ), between an image I t−k and a reference image for said image I t−k , which precedes said image I t−k in the video sequence; calculation of a second distance D(I t−2k ), between an image I t−2k and a reference image for said image I t−2k , which precedes said image I t−2k in the video sequence; calculation of a third distance D(I t−3k ), between an image I t−3k and a reference image for said image I t−3k , which precedes said image I t−3k in the video sequence; calculation of a criterion C′ indicating whether said second distance D(I t−2k ) is significantly greater than the largest of the first and third distances, D(I t−k ) and D(I t−3k ); decision, according to said criterion C′, on the belonging of the image I t−2k to an abrupt transition.
