Paper Abstract

Algorithms for the rapid correction of geometric distortions in digital images are evaluated. A flexible approximate piece-wise linear algorithm is described which can be implemented in near real time hardware. The expansion or compression of lines of digital imagery is achieved by repeating or deleting selected pixels. These pixels are chosen such that the error in the transformation does not exceed one quarter of a pixel The performance of this approach is compared with more sophisticated algorithms.
