Spline Function Approximation Techniquesnfor Image Geometric Distortion Representation

摘要

A considerable amount of interest has recently developed in the correction of spatial image distortions for registration of multitemporal remote sensor imagery [1, 2, 3]. The problem arises in the case where a scene is imaged at two or more times under varying sensor states. It is desired that the multiple images be geometrically registered so that when converted to digital form they can be analyzed as a multidimensional image vector using computer techniques.
