MergeMertens
import { MergeMertens } from '@banou/opencv-wasm'Use after await initOpenCV(). See the initialization and named imports guide.
Native object: release it with using or delete(). Factories can return null; check before calling methods. Inherits 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 [MK07] .
Constructors and members
clone
Create another handle to the same native object. This retains the object without copying its pixels or algorithm state; dispose both handles separately.
clone(): this;The this result.
process
MergeMertens.process: Merges images.
process(src: MatVector, dst: Mat, times: Mat, response: Mat): void;srcvector of input images
dstOutput destination, filled by the native operation. result image
timesvector of exposure time values for each image
response256x1 matrix with inverse camera response function for each pixel value, it should have the same number of channels as images.
process1
Short version of process, that doesn't take extra arguments.
process1(src: MatVector, dst: Mat): void;srcvector of input images
dstOutput destination, filled by the native operation. result image
getContrastWeight
Return the contrast weight configured on this MergeMertens object.
getContrastWeight(): number;The number result.
setContrastWeight
Set the contrast weight used by this MergeMertens object.
setContrastWeight(contrast_weiht: number): void;contrast_weihtcontrast weiht argument (number).
getSaturationWeight
Return the saturation weight configured on this MergeMertens object.
getSaturationWeight(): number;The number result.
setSaturationWeight
Set the saturation weight used by this MergeMertens object.
setSaturationWeight(saturation_weight: number): void;saturation_weightsaturation weight argument (number).
getExposureWeight
Return the exposure weight configured on this MergeMertens object.
getExposureWeight(): number;The number result.
setExposureWeight
Set the exposure weight used by this MergeMertens object.
setExposureWeight(exposure_weight: number): void;exposure_weightexposure weight argument (number).
