Class HOGParameters

Object
org.anchoranalysis.bean.AnchorBean<HOGParameters>
org.anchoranalysis.plugin.opencv.bean.feature.HOGParameters
public class HOGParameters
extends org.anchoranalysis.bean.AnchorBean<HOGParameters>
Parameters for calculating a HOG Descriptor covering window-size, block-size etc.

This class should implement a meaningful Object.equals(Object) and hashCode() on its properties as it may be used a CalculationPart. The interpolator) is not considered.

  • Constructor Details

    • HOGParameters

      public HOGParameters​(org.anchoranalysis.image.bean.interpolator.Interpolator interpolator)
      Creates with a particular Interpolator.
      Parameters:
      interpolator - the interpolator.

    • HOGParameters

      public HOGParameters()

  • Method Details

    • sizeDescriptor

      public int sizeDescriptor​(org.anchoranalysis.spatial.box.Extent imageSize)
      Calculates the size of the descriptor will be for a given image.

      It assumes the window is equal to the image-size.

      Parameters:
      imageSize - the size of the image (and window).
      Returns:
      the size of the descriptor needed.

    • createDescriptor

      public org.opencv.objdetect.HOGDescriptor createDescriptor​(org.anchoranalysis.spatial.box.Extent imageSize)
      Creates an empty HOGDescriptor to describe an image of a particular size.
      Parameters:
      imageSize - the size of the image.
      Returns:
      the descriptor, not yet computed with meaningful values.

    • checkSize

      public void checkSize​(org.anchoranalysis.spatial.box.Extent extent) throws org.anchoranalysis.feature.calculate.FeatureCalculationException
      Throws an exception if an image of size extent cannot be described by these parameters.
      Parameters:
      extent - the size of the image to check.
      Throws:
      org.anchoranalysis.feature.calculate.FeatureCalculationException - if the image is inappropriately sized for these parameters.
