Systems and methods for image fusion

A method for image fusion, implemented on a computing device including at least one processor and at least one storage medium, the method comprising:

• obtaining a first image including a plurality of first pixels, the first image being generated by a first imaging channel;
• obtaining a second image including a plurality of second pixels, the second image being generated by a second imaging channel distinct from the first imaging channel, each of the plurality of second pixels corresponding to one of the plurality of first pixels;
• classifying the plurality of first pixels into different categories, the different categories at least including a first category and a second category;
• and
• fusing the first image with the second image based on a fusion operation between each of the plurality of first pixels and its corresponding second pixel to generate a fused image, wherein the fusion operation associated with a first pixel belonging to the first category and the fusion operation associated with a first pixel belonging to the second category are performed according to different fusion rules.

A non-transitory computer readable medium, comprising executable instructions that, when executed by at least one processor, directs the at least one processor to perform a method for image fusion, the method comprising:

• obtaining a first image including a plurality of first pixels, the first image being generated by a first imaging channel;
• obtaining a second image including a plurality of second pixels, the second image being generated by a second imaging channel distinct from the first imaging channel, each of the plurality of second pixels corresponding to one of the plurality of first pixels;
• classifying the plurality of first pixels into different categories, the different categories at least including a first category and a second category;
• and
• fusing the first image with the second image based on a fusion operation between each of the plurality of first pixels and its corresponding second pixel to generate a fused image, wherein the fusion operation associated with a first pixel belonging to the first category and the fusion operation associated with a first pixel belonging to the second category are performed according to different fusion rules.
