Detailed Description

Pixels are weighted using contrast, saturation and well-exposedness measures, than images are combined using laplacian pyramids.

The resulting image weight is constructed as weighted average of contrast, saturation and well-exposedness measures.

The resulting image doesn't require tonemapping and can be converted to 8-bit image by multiplying by 255, but it's recommended to apply gamma correction and/or linear tonemapping.

For more information see [189] .

process() [1/2]

virtual void cv::MergeMertens::process ( InputArrayOfArrays  src, OutputArray  dst  )

pure virtual

Python:
	cv.MergeMertens.process(	src, times, response[, dst]	) ->	dst
	cv.MergeMertens.process(	src[, dst]	) ->	dst

Short version of process, that doesn't take extra arguments.

Parameters

src	vector of input images
dst	result image

process() [2/2]

virtual void cv::MergeMertens::process ( InputArrayOfArrays  src, OutputArray  dst, InputArray  times, InputArray  response  )

pure virtual

Python:
	cv.MergeMertens.process(	src, times, response[, dst]	) ->	dst
	cv.MergeMertens.process(	src[, dst]	) ->	dst

Merges images.

Parameters

src	vector of input images
dst	result image
times	vector of exposure time values for each image
response	256x1 matrix with inverse camera response function for each pixel value, it should have the same number of channels as images.

Implements cv::MergeExposures.
