Claim 14:
15. A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, direct the at least one processor to perform a method, the method comprising:
obtaining, by a first processor, a first image and a second image of a target region;
obtaining a low-frequency component and a high-frequency component of the first image;
obtaining a low-frequency component and a high-frequency component of the second image;
fusing the low-frequency component of the first image and the low-frequency component of the second image based on a weight coefficient of the low-frequency component of the first image and a weight coefficient of the low-frequency component of the second image;
fusing the high-frequency component of the first image and the high-frequency component of the second image based on a weight coefficient of the high-frequency component of the first image and a weight coefficient of the high-frequency component of the second image; and
determining, based on a fused low-frequency component and a fused high-frequency component, a fused image;
identifying, by a second processor, a region of interest (ROI) associated with a target object in the first image; and
generating, by the second processor, a target image by fusing information associated with the ROI in the first image and the fused image.
