Method Detail

discreteGaussian

public static <T extends ImageSingleBand> PyramidDiscrete<T> discreteGaussian(int[] scaleFactors,
                                                              double sigma,
                                                              int radius,
                                                              boolean saveOriginalReference,
                                                              Class<T> imageType)

Creates an updater for discrete pyramids where a Gaussian is convolved across the input prior to sub-sampling.

Parameters:

imageType - Type of input image.

sigma - Gaussian sigma. If < 0 then a sigma is selected using the radius.

radius - Radius of the Gaussian kernel. If < 0 then the radius is selected using sigma.

Returns:

PyramidUpdaterDiscrete

floatGaussian

public static <T extends ImageSingleBand> PyramidFloat<T> floatGaussian(double[] scaleFactors,
                                                        double[] sigmas,
                                                        Class<T> imageType)

Creates an updater for float pyramids where each layer is blurred using a Gaussian with the specified sigma. Bilinear interpolation is used when sub-sampling.

Parameters:

imageType - Type of image in the pyramid.

sigmas - Gaussian blur magnitude for each layer.

Returns:

PyramidUpdaterFloat

scaleSpacePyramid

public static <T extends ImageSingleBand> PyramidFloat<T> scaleSpacePyramid(double[] scaleSpace,
                                                            Class<T> imageType)

Constructs an image pyramid which is designed to mimic a GaussianScaleSpace. Each layer in the pyramid should have the equivalent amount of blur that a space-space constructed with the same parameters would have.

Parameters:

scaleSpace - The scale of each layer and the desired amount of blur relative to the original image

imageType - Type of image

Returns:

Image pyramid

scaleSpace

public static <T extends ImageSingleBand> PyramidFloat<T> scaleSpace(double[] scaleSpace,
                                                     Class<T> imageType)
