Abstract
A computer-implemented method for determining whether a video frame is of a 3D TB type (Top-Bottom) or a 3D LR type (Left-Right) frame, characterized in that it comprises the steps of: receiving a video frame (100); extracting at least three portions (121-124) of the frame, each portion belonging to a distinct quarter of the frame (100, 120) and being positioned at the same fragment of the quarter; calculating color histograms for each portion (121-124); comparing the color histograms of at least two different pairs of portions; generating a frame type indicator based on the result of comparison of the color histograms.
