```
    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.
  - collectGarbage
```
public void collectGarbage()
```
  - setClipLimit
```
public void setClipLimit(double clipLimit)
```
    Sets threshold for contrast limiting.
    
    Parameters:
    
    clipLimit - threshold value.
  - 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.
  - finalize
```
protected void finalize()
                 throws java.lang.Throwable
```
    Overrides:
    
    finalize in class Algorithm
    
    Throws:
    
    java.lang.Throwable
