Abstract
Systems and methods are provided for improved two pass resampling in a computing system. The systems and methods address both bottleneck problem(s) and aliasing problem(s) to improve upon prior art two pass resampling techniques. In view of both bottleneck problem(s) and aliasing problem(s), for each of four possibilities associated with two pass resampling, the four possibilities being (1) pre-rotating the 2-D data and performing row-first processing (2) pre-rotating the 2-D data and performing column-first processing, (3) not pre-rotating the 2-D data and performing row-first processing and (4) not pre-rotating the 2-D data and performing column-first processing, the bottleneck error and the aliasing error associated with the possibility are calculated. Also, for each possibility, a value is computed based upon the bottleneck error and the aliasing error. The choice of the four possibilities is then selected in accordance with a comparison of the values.
