  • Patent number: 10051286
    Abstract: Devices and methods for generating a three-dimensional video stream starting from a sequence of video images. The sequence includes a first view (V0), at least one second view (V1) of a scene, and a depth map (D0) of said first view (V0), or a disparity map of said at least one second view (V1) with respect to the first view (V0). At least one occlusion image (O1) including the occluded pixels of said second view (V1) is obtained by starting from said depth map (D0) or from said disparity map. A compacted occlusion image (OC1)is generated by spatially repositioning said occluded pixels of said at least one occlusion image (O1), so as to move said pixels closer to one another. The three-dimensional video stream may include said first view (V0), said depth map (D0) or said disparity map, and said at least one compacted occlusion image (OC1).

  • Patent number: 10049502
    Abstract: A method for edge correction of images of a three-dimensional video content, the video content including at least one original view image and at least one depth or disparity map, the method including the following steps: detecting edges in at least one original view image for obtaining original edges; warping the original edges according to the depth or disparity map; detecting a set of warped edges altered by the warping process; and correcting the altered edges for obtaining corrected edges.

  • Patent number: 10038890
    Abstract: A method is described for generating a color image composed of a plurality of components (Y, U, V) by starting from at least one depth or disparity map (DM1, DM2), wherein a first set of pixels of said at least one depth or disparity map (DM1, DM2) is entered into the luminance component (Y) of said color image, and wherein a second and a third sets of pixels of said at least one depth or disparity map (DM1, DM2) are entered into the two chrominance components (U, V) of said color image.
