public class AlgorithmWSinc
extends AlgorithmBase

Sinc function windowed with Hanning window function used for interpolation This function will create images with greater maximums and lower minimums than the original image, so if the input image type is BYTE or UBYTE, the output image type should be a SHORT. Notice that clamping to 0 and 255 is used with ARGB images.

This is an example of a cardinal basis function. The cardinal basis function centered at a given original grid point is the definition of how an image that is 1 at that grid point and 0 at all others is to be interpolated into intermediate points. The final image is then constructed by adding together all the basis functions from each original grid point, each one scaled by the intensity at its original grid point. Since a cardinal basis function is zero at all other original grid points except the one at which it is based, interpolation that falls exactly onto an original grid point will always preserve the original value.
