Abstract

Various embodiments are directed to a method for determining a disparity value for an image element in a row of a first image with respect to a second image. The method may include determining, for each disparity candidate of a plurality of disparity candidates, a cost value based on an intensity difference between the image element in the first image and a corresponding image element in the second image determined using the respective disparity candidate; determining, for each disparity candidate of the plurality of disparity candidates, an amended cost value based on the cost value of the image element and at least one of a first term and a second term, said first term being based on disparity values of one or more image elements from one or more preceding rows in the first image, and said second term being based on a disparity value of a corresponding image element in a preceding first image having the same position as the image element in the first image; and determining a disparity candidate out of the plurality of disparity candidates as the disparity value of the image element in the first image based on the amended cost values of the plurality of disparity candidates.
