Method Details

__fromPtr__

public static CLAHE __fromPtr__(long addr)

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.

getClipLimit

public double getClipLimit()

setClipLimit

public void setClipLimit(double clipLimit)

Sets threshold for contrast limiting.

Parameters:

clipLimit - threshold value.

getTilesGridSize

public Size getTilesGridSize()

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.

collectGarbage

public void collectGarbage()
