Abstract
A set of C++ classes have been written for finding an interpolated scalar value at any point on a rectangular grid in one, two or three dimensions. The grid is considered to be composed of pixels or voxels and the known values are considered to be defined in one of two ways, either 1) the values of a continuous field measured at the center of each pixel or voxel, or 2) the integrated (averaged) values of the field for each pixel or voxel. (The classes include a method for interpolation using known values defined at arbitrary positions rather than on a rectangular grid, but this part of the package has not been tested.) This packages has implementation of interpolation could be of general use, but the motivation has been for segmentation of medical images, hence, some design choices have been made for that specific application.
