Systems and methods for fusing infrared image and visible light image

摘要

A system and a method for image fusion are provided. The method may comprise: obtaining a visible light image and an infrared image relating to a same scene; performing a first decomposition to the visible light image to obtain a first high-frequency component of the visible light image and a first low-frequency component of the visible light image; performing a first decomposition to the infrared image to obtain a first high-frequency component of the infrared image and a first low-frequency component of the infrared image; fusing the first high-frequency component of the visible light image and the first high-frequency component of the infrared image based on a first algorithm to generate a first fused high-frequency component; and performing reconstruction based on the first fused high-frequency component, the first low-frequency component of the visible light image, and the first low-frequency component of the infrared image to generate a fused image.
