System for spatially transforming images
Abstract
An image processing system includes a control system comprising a processor (1308) generating under the control of an operator's panel (1310) image transformation commands. A controller (1314) stores at knot points parameters indicating commanded control conditions. The controller provides image transformation parameters for a sequence of fields. The image transformation parameters at each field corresponding to a knot are indicative of the stored parameters and at intermediate fields the image transformation parameters are generated as a cubic spline interpolation between stored parameters.
