像素级融合又可根据空间域和变换域对各种方法进行分类： 如， 空间域融合

Fusion performed according to pixel-level turn transform domain and the spatial domain of the various classification methods: e.g., spatial domain fusion method includes filtering logic, <br>the weighted average method, principal component analysis (PCA) method, HIS spatial image fusion, fusion feathering and the like; fusion transform domain image comprises a multi <br>-resolution fusion method (i.e., pyramid decomposition method), a wavelet transform method.

Pixel-level fusion can also classify methods according to spatial domains and transformation domains: for example, spatial domain fusion methods include logical filtering,<br>Weighted averaging method, main component analysis (PCA) method, HIS spatial image fusion method, feather fusion method, etc.<br>Resolution fusion (i.e. pyramid decomposition), wavelet transformation, etc.
