Preserving Edge Position During Resampling
David M. Bell, Jordan Bryan · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1990
A technique for designing digital filters that preserve edge position during image resampling is described. The technique consists of designing a set of separable filters, with each filter designed as an all pass filter with nonlinear phase and a set constrained amplitude. The technique is compared to existing techniques.
