Abstract
An example method includes receiving first and second images from a first and second imager. The method further includes determining first correlation scores between a target pixel from the first image and respective pixels from the second image based on a first similarity measure. The method also includes identifying a candidate matching pixel to the target pixel based on the first correlation scores. The method further includes determining second correlation scores between the target pixel and each of the candidate matching pixel, a left neighboring pixel, and a right neighboring pixel based on a second similarity measure. The method also includes determining whether the candidate matching pixel is better correlated to the target pixel than each of the neighboring pixels based on the second correlation scores. After determining that the candidate matching pixel is better correlated, the method further includes determining a disparity value by interpolating the second correlation scores.
