dc.description.abstract | This paper describes an efficient and relatively simple new prefiltering algorithm called quadrature prefiltering. Quadrature prefiltering provides very high quality suppression of aliasing artifacts at reasonable cost for images which would require extremely high super sampling rates using either regular super sampling or stochastic sampling to obtain equivalent antialiasing performance and signal to noise ratio. The new algorithm allows arbitrary filter kernels including non-radially symmetric filter kernels while only requiring a two dimensional look up table. Previous algorithms have required a three dimensional lookup table or radially symmetric filter kernels. It is only slightly more complicated to implement than box prefiltering, a commonly used antialiasing prefilter, but it generates images with much less visible aliasing artifacts. | en |
