Claim 19:
20. A non-transitory computer readable medium, comprising at least one set of instructions, wherein when executed by at least one processor, the at least one set of instructions direct the at least one processor to effectuate a method, the method comprising:
obtaining a first image and a second image of a same scene, wherein pixels of at least a part of the first image corresponding to pixels of at least a part of the second image;
generating, based on the first image, a first low-frequency image corresponding to a low-frequency component of the first image, the first low-frequency image including a plurality of first pixels;
generating, based on the second image, a first high-frequency image corresponding to a high-frequency component of the second image, the first high-frequency image including a plurality of second pixels, the plurality of second pixels corresponding to the plurality of first pixels;
determining, based on the first low-frequency image and the first high-frequency image, a featuring region in the first high-frequency image, wherein the featuring region and a region of the first image that corresponds to the featuring region have different luminance transition trends;
correcting the second pixels in the featuring region based at least in part on the first low-frequency image; and
generating a fusion image based at least in part on the first low-frequency image and the first high-frequency image.
