Under different classifications, image fusion algorithms can consist of space domain and transform domain, or pixel-level, feature-level and decision-making level.

根据图像融合分类的不同，图像融合的算法可分为空域、变换域融合算法，或像素级、特征级和决策级融合算法。

According to the different abstract extent of information, from low to high, it can also be divided into three levels: pixel-level, feature-level and decision-making level.

也可以根据信息抽象程度的不同，从低到高分为像素级、特征级和决策级融合三个层次。
