Abstract
A computer-implemented method for determining a video frame type, comprising the steps of receiving a video frame and analyzing the contents of consecutive lines of the video frame in frequency domain by detecting a number of LR-type lines (μ) of the video frame for which the left half of the line is phase-correlated with the right half of the line, detecting an LR mean error (ε) as a function of the difference between the values of Fourier transform coefficients for the left half of the line and the right half of the line, detecting a number of TB lines (μ) of a top half of the frame which are phase-correlated with lines of a bottom half of the frame and detecting a TB mean error (ε) as a function of the difference between the values of Fourier transform coefficients for the lines of the top half of the frame and the lines of the bottom half of the frame. The method further comprises the step of calculating probability coefficients specifying that the frame type is a TB-type (p) or LR-type (p) 3D frame as a function of the LR mean error (ε) and the TB mean error (ε) and calculating a probability coefficient specifying that the frame type is a 2D frame as a function of the number of LR-type lines (μ) and the number of TB lines (μ).
