Class MergeMertens

java.lang.Object

org.opencv.core.Algorithm

org.opencv.photo.MergeExposures

org.opencv.photo.MergeMertens

public class MergeMertens
extends MergeExposures

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 CITE: MK07 .

process

public void process(java.util.List<Mat> src,
                    Mat dst)

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

Parameters:

src - vector of input images

dst - result image

process

public void process(java.util.List<Mat> src,
                    Mat dst,
                    Mat times,

Description copied from class: MergeExposures

Merges images.

Overrides:

process in class MergeExposures

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.
