- This paper derives the stereo-defocus equation, which describes an explicit relationship between stereo disparity and blur and thereby suggests a method for depth estimation by combining the two quantities. Because disparity and blur are two different aspects of the same 3D point, a direct geometric relationship in the image plane exists between them.
Ordinary methods usually separately compute disparity from stereo image pairs, and a blur circle from a defocused image, and then to combine them to achieve depth estimation. Instead, the stereo-defocus equation can
be used as a constraint to stereo matching and blur estimation. We confirmed the validity of this concept by experiments with stereo matching that were constrained by blur information.
