Conditional Random Field-Guided Multi-Focus Image Fusion [PDF]
Journal of Imaging, 2022 Multi-Focus image fusion is of great importance in order to cope with the limited Depth-of-Field of optical lenses. Since input images contain noise, multi-focus image fusion methods that support denoising are important.

Multi-Focus Color Image Fusion Based on Quaternion Multi-Scale Singular Value Decomposition [PDF]
Frontiers in Neurorobotics, 2021 Most existing multi-focus color image fusion methods based on multi-scale decomposition consider three color components separately during fusion, which leads to inherent color structures change, and causes tonal distortion and blur in the fusion results.
