RECONSTRUCTION OF MISSING DATA POINT FROM SPARSE SAMPLES DURING GRAPHICS PROCESSING USING CUBIC SPLINE POLYNOMIALS

摘要

A graphics system includes a reconstruction unit that utilizes higher order polynomials, such as cubic splines, to reconstruct missing pixel data. The computational work to perform interpolation with higher order polynomials, such as cubic splines, is reduced by pre-calculating weights for each sparse sample pattern. The pre-calculated weights may be stored as stencils and used during runtime to perform interpolation.
