The performed experiments support a few general conclusions, such as about the relation between 1D- or 2D-window based cost functions, the use of zero-mean normalization, the census cost function, or the use of B-splines for subpixel accurate cost calculation.Copyright Computer Science Department, The University of Auckland.
