Abstract:
1. A method for determining a disparity field of an image of a set of multi-view images, the method comprising: determining pixel correspondences between the image and another image of the set of multi-view images with a multi-pass disparity estimator; determining a vertical disparity field from at least a subset of the determined pixel correspondences in an earlier pass of the multi-pass disparity estimator; smoothing the vertical disparity field; estimating a vertical component of a distortion field from the smoothed vertical disparity field; and determining a horizontal disparity field in a later pass of the multi-pass disparity estimator, wherein the estimated vertical 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 by keeping the estimated vertical component of the distortion field fixed during subsequent passes of the multi-pass disparity estimator.
