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.

createTonemapReinhard(gamma: number, intensity: number, light_adapt: number, color_adapt: number): TonemapReinhard | null;

gamma

gamma value for gamma correction. See createTonemap

intensity

result intensity in [-8, 8] range. Greater intensity produces brighter results.

light_adapt

light adaptation in [0, 1] range. If 1 adaptation is based only on pixel value, if 0 it's global, otherwise it's a weighted mean of this two cases.

color_adapt

chromatic adaptation in [0, 1] range. If 1 channels are treated independently, if 0 adaptation level is the same for each channel.

Returns

The TonemapReinhard | null result.
