Class PyramidFloatScale<T extends ImageGray>

java.lang.Object

boofcv.struct.pyramid.ImagePyramidBase<T>

boofcv.struct.pyramid.PyramidFloat<T>

boofcv.alg.transform.pyramid.PyramidFloatScale<T>

All Implemented Interfaces:

ImagePyramid<T>

public class PyramidFloatScale<T extends ImageGray>
extends PyramidFloat<T>

Updates each layer in a PyramidFloat by rescaling the layer with interpolation. Unlike PyramidFloatGaussianScale, no additional blurring is done between layers.

                         double[] scaleFactors,
                         java.lang.Class<T> imageType)

Method Detail

process

public void process(T input)

Description copied from interface: ImagePyramid

Constructs the image pyramid given the input image.

getSampleOffset

public double getSampleOffset(int layer)

Description copied from interface: ImagePyramid

Returns the sampling offset. Both x and y axises are assumed to have the same offset. See comment in constructor above.

Parameters:

layer - Layer in the pyramid

Returns:

Sampling offset in pixels.

getSigma

public double getSigma(int layer)

No blur is applied to the image

Parameters:

layer - Layer in the pyramid

Returns:

scale
