      Radian from pi to -pi
    • intensity

      public double intensity
      Used to judge how good of a fit the corner is to an ideal chessboard corner. Higher the value the more x-corner like. Computed on a per-feature basis and should be more accurate than the x-corner detector intensity.
    • contrast

      public double contrast
      The white region subtracted the black region at the chessboard corner. Can be used later on for locally adaptive thresholds
    • edgeIntensity

      public double edgeIntensity
      Value of smallest Eigen value in edge detector
    • edgeRatio

      public double edgeRatio
      Ratio of smallest and largest Eigen values in edge detector
    • level1

      public int level1
      The first and second level in the pyramid the corner was seen at. level1 <= level2
    • level2

      public int level2
      The first and second level in the pyramid the corner was seen at. level1 <= level2
    • levelMax

      public int levelMax
      Level with the maximum corner intensity
    • first
