  • Reconstruction of de-interleaved views, using adaptive interpolation based on disparity between the views for up-sampling
    Patent number: 8605782
    Abstract: Method for reconstructing interleaved views of a 3D image comprising the steps of: receiving interleaved views of a 3D image, de-interleaving said interleaved views into a first view and a second view, each de-interleaved view comprising missing pixels, at each pixel location determining an amount of disparity between said first and second views, for each view interpolating each missing pixel based on the amount of disparity determined at the associated pixel location, wherein when the determined disparity is above a predetermined disparity threshold, the missing pixel value is interpolated from the data of the view to be interpolated only (i.e. the view comprising said missing pixel value), and when the determined disparity is at or below said predetermined disparity threshold, the missing pixel value is interpolated from the data of both views.
