Some Useful Definitions

This section defines some terms and concepts used in this chapter.

accuracy: A parameter you can set that will control the accuracy of the Image Warp tool mapping. Higher accuracy requires a larger mapping table in memory, and longer execution times.

calibration: A procedure to produce a transform that establishes the relationship between pixels in an image and physical units such as microns. Calibration transforms can also correct for distortion in an image.

destination mask: Part of the Image Warp tool that indicates which pixels in the destination window contain mapped pixels from the source image.

transform: A C++ class that can perform mapping between two coordinate systems. Most often used in CVL to map between image space and client (physical) space. Transform mapping can be linear or nonlinear.

warp: A term used by the Image Warp tool for the mapping a distorted source image to a corrected destination image.

warp transform: The transform used to train the Image Warp tool.

window: A rectangular region of a root image in a pel buffer. A subset of the entire image.
