1. A method for generating a glare-free image, the method comprising:
acquiring an RGB image of a scene in a visible wavelength range;
acquiring an infrared (IR) image of the scene in an IR wavelength range;
transforming the RGB image to a YUV image;
based on a luminance component of the YUV image, identifying a glare region in the YUV image;
identifying, in the IR image, a corresponding region to the glare region in the YUV image; and
substituting, in the luminance component of the YUV image, pixel values in the glare region with pixel values of the corresponding region in the IR image.
