Member Function Documentation

apply()

virtual void cv::CLAHE::apply ( InputArray  src, OutputArray  dst  )

pure virtual

Python:
	cv.CLAHE.apply(	src[, dst]	) ->	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.

collectGarbage()

virtual void cv::CLAHE::collectGarbage ( )

pure virtual

Python:
	cv.CLAHE.collectGarbage(		) ->	None

getClipLimit()

virtual double cv::CLAHE::getClipLimit ( ) const

pure virtual

Python:
	cv.CLAHE.getClipLimit(		) ->	retval

Returns threshold value for contrast limiting.

getTilesGridSize()

virtual Size cv::CLAHE::getTilesGridSize ( ) const

pure virtual

Python:
	cv.CLAHE.getTilesGridSize(		) ->	retval

Returns Size defines the number of tiles in row and column.

setClipLimit()

virtual void cv::CLAHE::setClipLimit ( double  clipLimit )

pure virtual

Python:
	cv.CLAHE.setClipLimit(	clipLimit	) ->	None

Sets threshold for contrast limiting.

Parameters
