    • apply

      public void apply(Mat src, Mat dst)
      Equalizes the histogram of a grayscale image using Contrast Limited Adaptive Histogram Equalization.
      Parameters:
      src - Source image of type CV_8UC1 or CV_16UC1.
      dst - Destination image.

    • setClipLimit

      public void setClipLimit(double clipLimit)
      Sets threshold for contrast limiting.
      Parameters:
      clipLimit - threshold value.

    • getClipLimit

      public double getClipLimit()

    • setTilesGridSize

      public void setTilesGridSize(Size tileGridSize)
      Sets size of grid for histogram equalization. Input image will be divided into equally sized rectangular tiles.
      Parameters:
      tileGridSize - defines the number of tiles in row and column.

    • getTilesGridSize

    • setBitShift

      public void setBitShift(int bitShift)
      Sets bit shift parameter for histogram bins.
      Parameters:
      bitShift - bit shift value (default is 0).

    • getBitShift

      public int getBitShift()
      Returns the bit shift parameter for histogram bins.
      Returns:
      current bit shift value.
