Claim 0:
1. A method for generating a fusion image, implemented on a device including at least one processor and at least one storage device, 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.
