<p>A computer-implemented method for determining a video frame type, comprising the steps of receiving a video frame matrix describing the contents of the video frame, calculating a two-dimensional Fourier Transform spectrum (X mn ) of the contents of the video frame matrix, determining whether the spectrum (X mn ) is periodic with a period equal to 2 in a horizontal and/or vertical direction, classifying the video frame as a horizontal LR-type stereoscopic frame if the spectrum (X mn ) is determined as periodic in the horizontal direction and/or classifying the video frame as a vertical TB-type stereoscopic frame if the spectrum (X mn ) is determined as periodic in the vertical direction and classifying the video frame as a mono frame otherwise.</p> |
