  • Method Details

    • setImage

      void setImage(T image)
      Specified the image which is to be processed.
      Parameters:
      image - The image which contains the features.

    • process

      boolean process(double x, double y, double orientation, double radius, Desc description)

      Extract a description of the local image at the given point, scale, and orientation.

      WARNING: Check the returned value to make sure a description was actually computed. Some implementations might now allow features to extend outside the image border and will return false.

      Parameters:
      x - Coordinate of the point.
      y - Coordinate of the point.
      orientation - Direction the feature is pointing at in radians. 0 = x-axis PI/2 = y-axis
      radius - Radius of the detected object in pixels.
      description - (output) Storage for extracted feature. Use DescriptorInfo.createDescription() to create descriptor.
      Returns:
      true if a descriptor can be computed or false if not.

    • isScalable

      boolean isScalable()
      If size information is used when computing the descriptor.
      Returns:
      true is the radius is used when computing the descriptor or false if not

    • isOriented

      boolean isOriented()
      True if the descriptor uses orientation information.
      Returns:
      if orientation needs to be provided or not

    • getImageType

      ImageType<T> getImageType()
      Description of the type of image it can process
      Returns:
      ImageDataType

    • getCanonicalWidth

      double getCanonicalWidth()
      Returns the width of the square (or approximation of) sample region at a scale of one. When multiplied by the scale, pixels outside of the square region should not influence the descriptor's value.
      Returns:
      width of descriptor at a scale of one
