      protected OrientationIntegralBase​(double objectRadiusToScale, int sampleRadius, double period, int kernelWidth, double weightSigma, boolean assignDefaultRadius, Class<II> integralType)
      Configure orientation estimation.
      sampleRadius - The radius of samples that it will do. Typically 6.
      period - How often the image is sampled in pixels at canonical size. Internally, this value is scaled by scaledPeriod = period*objectRadius/sampleRadius. Typically 1.
      kernelWidth - How wide of a kernel should be used to sample. Try 4
      weightSigma - Sigma for weighting. Set to zero for unweighted, negative to use sampleRadius.
      assignDefaultRadius - If true it will set the object's radius to a scale of 1
