    • discreteGaussian

      public static <T extends ImageBase<T>> PyramidDiscrete<T> discreteGaussian​(ConfigDiscreteLevels configLevels, double sigma, int radius, boolean saveOriginalReference, ImageType<T> imageType)
      Creates an updater for discrete pyramids where a Gaussian is convolved across the input prior to sub-sampling.
      imageType - Type of input image.
      sigma - Gaussian sigma. If < 0 then a sigma is selected using the radius. Try -1.
      radius - Radius of the Gaussian kernel. If < 0 then the radius is selected using sigma. Try 2.
    • floatGaussian

      public static <T extends ImageGray<T>> PyramidFloat<T> floatGaussian​(double[] scaleFactors, double[] sigmas, Class<T> imageType)
      Creates a float pyramid where each layer is blurred using a Gaussian with the specified sigma. Bilinear interpolation is used when sub-sampling.
      scaleFactors - The scale factor of each layer relative to the previous layer. Layer 0 is relative to the input image.
      sigmas - Gaussian blur magnitude for each layer.
      imageType - Type of image in the pyramid.
    • scaleSpacePyramid

      public static <T extends ImageGray<T>> 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.
      scaleSpace - The scale of each layer and the desired amount of blur relative to the original image
      imageType - Type of image
    • scaleSpace

      public static <T extends ImageGray<T>> PyramidFloat<T> scaleSpace​(double[] scaleSpace, Class<T> imageType)
      Constructs a scale-space image pyramid. Each layer in the pyramid is the same size as the input image but has a different amount of blur applied to it.
      Type Parameters:
      T - Type of image
      scaleSpace - Amount of blur applied to each layer in the pyramid relative to the input image.
      imageType - Type of image
      Scale-space image pyramid
