Robust sparse representation based multi-focus image fusion with dictionary construction and local spatial consistency
作者：
Highlights：
• A RSR model is introduced for multi-focus image fusion.
• Local consistency among adjacent patches is considered in the fusion method.
• A dictionary is constructed for RSR by using “row-sparsity” constraint.
• The fusion method introduces few spatial artifacts to the fused image.
• The fusion method has high computation efficiency.
