Abstract:
The disparity pyramid is a proposed solution for the
problem of disparity estimation using a stereoscopic pair
of images. This pyramid can be classified within the class
of data-dependent irregular pyramids. The hierarchy
of the pyramid is achieved by successive calculations
of a set of levels. These calculations are done
over a disparity range to get the difference in intensities
between the two images. Unlike some other pyramids,
and according to input values and/or distances between
disparity vectors, the top level of this pyramid may consist
of more than one cell. Thus, in terms of geometry,
its shape looks like an incomplete pyramid with a at
top level and irregular sides.
