Use after await initOpenCV(). See the initialization and named imports guide.

Explore visually: HDR merging and tone mapping →

Combine exposure information or fuse well-exposed regions, then map the result into a displayable range.

VISUAL WALKTHROUGHPhotography

REFERENCE INPUTBracketed exposures

Different exposures preserve useful information in different intensity ranges.

RESULTMap the merged result for display

The drawing illustrates combined visibility. Radiance estimation and exposure fusion have different outputs; tone mapping applies to a radiance result.

Illustrative example. The stages explain the method; they are not a live OpenCV execution.

Creates MergeMertens object

createMergeMertens(contrast_weight: number, saturation_weight: number, exposure_weight: number): MergeMertens | null;

4 available overloads

createMergeMertens(): MergeMertens | null;

createMergeMertens(contrast_weight: number): MergeMertens | null;

createMergeMertens(contrast_weight: number, saturation_weight: number): MergeMertens | null;

createMergeMertens(contrast_weight: number, saturation_weight: number, exposure_weight: number): MergeMertens | null;

contrast_weight

contrast measure weight. See MergeMertens.

saturation_weight

saturation measure weight

exposure_weight

well-exposedness measure weight

Returns

The MergeMertens | null result.
