Various warping transformation models are supported:

• Helmert

• Similitude

• Affine

• Projective

• Thin Plate Spline - No Residuals

• Polynomial

The unique design of Register lets you visually determine if the transformation model is accurate. Since base vector data is displayed over the target image, it is simple to identify inaccuracies in the model. To assist you in the warping process, Register displays statistical information about the accuracy of the transformation model. You can also dynamically change the transformation model and interactively edit the control points on the base document.

When the transformation model is accurate, as many images as necessary can be resampled. Resampling methods include nearest neighbor, bilinear interpolation, and cubic convolution.
