Image resampling in remote sensing and image visualization applications
Thomas J. Trainer, Fang-Kuo Sun · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1991
Imaging applications often require image warping in order to obtain a desired spatial effect. In implementing a warping technique, means for transforming and resampling the source data must be chosen. A forward or reverse transformation mapping can be selected, though interpolation is more accurate using the reverse format. When applying a noninvertible transformation, forward mapping becomes necessary. A technique called bin mapping introduces an intermediate storage mechanism which allows for precise interpolation while applying a forward transformation.
