Class BilinearPixel<T extends ImageSingleBand>

java.lang.Object

boofcv.alg.interpolate.BilinearPixel<T>

All Implemented Interfaces:

InterpolatePixel<T>, InterpolatePixelS<T>

Direct Known Subclasses:

ImplBilinearPixel_F32, ImplBilinearPixel_F64, ImplBilinearPixel_S16, ImplBilinearPixel_S32, ImplBilinearPixel_U8

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

Performs bilinear interpolation to extract values between pixels in an image. When a boundary is encountered the number of pixels used to interpolate is automatically reduced.
