boofcv.alg.interpolate

Class PolynomialPixel<T extends ImageSingleBand>

java.lang.Object

boofcv.alg.interpolate.PolynomialPixel<T>

All Implemented Interfaces:

InterpolatePixel<T>, InterpolatePixelS<T>

Direct Known Subclasses:

ImplPolynomialPixel_F32, ImplPolynomialPixel_I

public abstract class PolynomialPixel<T extends ImageSingleBand>
extends Object
implements InterpolatePixelS<T>

Polynomial interpolation using Neville's algorithm. First interpolation is performed along the horizontal axis, centered at the specified x-coordinate. Then a second pass is done along the vertical axis using the output from the first pass.

The code is unoptimized and the algorithm is relatively expensive.
