    摘要: A solution for determining a similarity or dissimilarity measure for a selected pixel of a first image relative to another selected pixel in a second image is described. The first image and the second image form a stereoscopic image pair or part of a multi-view image group. In a first step a first support window containing the selected pixel in the first image is determining. Then a second support window containing the selected pixel in the second image is determining. Subsequently one or more statistical properties of the selected pixel in the first image are calculated to define a probability distribution for the selected pixel in the first image. Finally, pixel similarity or dissimilarity between the first support window and the second support window is aggregated using only those pixels belonging to the probability distribution for the selected pixel in the first image with a probability above a defined minimum.

    摘要: A method and an apparatus for recovering a component of a distortion field of an image of a set of multi-view images are described. Also described are a method and an apparatus for determining a disparity field of an image of a set of multi-view images, which makes use of such method.In a first step pixel correspondences between the image and another image of the set of multi-view images are determined. A disparity field is then determined from at least a subset of the determined pixel correspondences. The disparity field is smoothed and the component of the distortion field is estimated from the smoothed disparity field. When determining a second disparity field the estimated component of the distortion field is taken into account when determining pixel correspondences between the image and another image of the set of multi-view images.

    摘要: The invention relates to a method and an apparatus for determining a disparity value for an object located in or to be placed into a stereoscopic image pair having an associated disparity map. First an area to be analyzed in one of the stereoscopic images is determined Then a histogram is built from disparity estimates of the associated disparity map that fall within the determined area. Subsequently a contiguous range of bins is searched in the histogram that also contains a sufficient number of pixels. Finally, a disparity estimate for the determined area is selected from the contiguous range of histogram bins.

    摘要: An apparatus and a method for refining a value of a similarity measure are described. A similarity measure is assigned to a pixel or a group of pixels of a disparity map, which is assigned to at least two stereo images each having a plurality of pixels. The similarity measure constitutes an estimate for a match quality of the pixel or the group of pixels. For refinement of the value of the similarity measure, the similarity measure between a pixel or a group of pixels in a first stereo image and a corresponding pixel or a group of corresponding pixels in a second stereo image is determined. A contrast value for the pixel or the group of pixels of the first or the second stereo image is determined and the value of the similarity measure is corrected by a correction value that is a function of the determined contrast value.
