      weightsList - the list of weight of each color; default: empty array

    • setWeightCoeff

      public void setWeightCoeff(double weightsCoeff)
      set WeightCoeff
      Parameters:
      weightsCoeff - the exponent number of L* component of the reference color in CIE Lab color space; default: 0

    • setMaxCount

      public void setMaxCount(int maxCount)
      set MaxCount
      Parameters:
      maxCount - used in MinProblemSolver-DownhillSolver; Terminal criteria to the algorithm; default: 5000;

    • setEpsilon

      public void setEpsilon(double epsilon)
      set Epsilon
      Parameters:

    • setRGB

      public void setRGB(boolean rgb)
      Set whether the input image is in RGB color space
      Parameters:
      rgb - If true, the model expects input images in RGB format. If false, input is assumed to be in BGR (default).
