Exposure fusion fuses multiple images taken at various exposure settings to a single image.
Exposure fusion is useful for obtaining high-quality images in high-dynamic-range scenes.
Existing exposure fusion methods have drawbacks such as high computational cost and generating low-contrast fusion results.
In particular, a problem common to many conventional methods is that these methods tend to suffer from the loss of image details due to pixel value clipping.
In this report, we propose an exposure fusion method based on brightness, contrast, and saturation adjustments for obtaining the high-quality image with suppressed loss of details.
The proposed method applies the pixel-wise fusion to the luminance of the input multi-exposure images by calculating the mean luminance value for each pixel.
Then, the brightness and contrast of the fused luminance image are adjusted using S-shape functions.
After that, the color enhancement using S-shape function is performed to generate the target saturation image.
Finally, the output color image is generated using the equi-hue plane in the RGB color space. |
