Abstract
A method and an apparatus for computing a parallax are provided. The method includes: obtaining a plurality of views of a pixel point; computing gradients in a plurality of directions of the pixel point in the plurality of view; computing a matching error corresponding to a parallax of the pixel point according to the gradients; and computing the parallax of the current pixel point according to the matching error. Through the method and the apparatus for computing a parallax, the accuracy of parallax estimation is increased.
