Class HOGParameters

Object
AnchorBean<HOGParameters>
HOGParameters
public class HOGParameters extends 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(Interpolator interpolator)
      Creates with a particular Interpolator.
      Parameters:
      interpolator - the interpolator.

    • HOGParameters

      public HOGParameters()

  • Method Details

    • sizeDescriptor

      public int sizeDescriptor(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(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(Extent extent) throws 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:
      FeatureCalculationException - if the image is inappropriately sized for these parameters.

    • equals

      public boolean equals(Object o)
      Overrides:
      equals in class Object

    • canEqual

      protected boolean canEqual(Object other)

    • hashCode

      public int hashCode()
      Overrides:
      hashCode in class Object

    • getWindowSize

      public SizeXY getWindowSize()
      The window-size as per OpenCV implementation. If not specified, the window is set to be the same size as the (possibly resized) image.

    • setWindowSize

      public void setWindowSize(SizeXY windowSize)
      The window-size as per OpenCV implementation. If not specified, the window is set to be the same size as the (possibly resized) image.

    • getBlockSize

      public SizeXY getBlockSize()
      The block-size as per OpenCV implementation (identical default-size).

    • setBlockSize

      public void setBlockSize(SizeXY blockSize)
      The block-size as per OpenCV implementation (identical default-size).

    • getBlockStride

      public SizeXY getBlockStride()
      The block-stride as per OpenCV implementation (identical default-size).

    • setBlockStride

      public void setBlockStride(SizeXY blockStride)
      The block-stride as per OpenCV implementation (identical default-size).

    • getCellSize

      public SizeXY getCellSize()
      The cell-size as per OpenCV implementation (identical default-size).

    • setCellSize

      public void setCellSize(SizeXY cellSize)
      The cell-size as per OpenCV implementation (identical default-size).

    • getNumberBins

      public int getNumberBins()
      The number of bins in each histogram for a cell.

    • setNumberBins

      public void setNumberBins(int numberBins)
      The number of bins in each histogram for a cell.

    • getInterpolator

      public Interpolator getInterpolator()
      The interpolator to use for scaling images.

    • setInterpolator

      public void setInterpolator(Interpolator interpolator)
      The interpolator to use for scaling images.
