Weighted Least Squares Based Detail Enhanced Exposure Fusion

Figure 12

Visual inspection of contrast and detail enhancement in multifocus image fusion. The free parameter 𝜆 in (15) and 𝑎 in (18) controls detail enhancement and sharpening, respectively. We are able to achieve aggressive detail enhancement and exaggeration, while avoiding artifacts. Clock image: (a) 𝜆=0.5, 𝑎=7, (b) 𝜆=0.5, 𝑎=12, (c) 𝜆=0.5, and 𝑎=17. Leaves image: (d) 𝜆=0.5, 𝑎=7, (e) 𝜆=0.5, 𝑎=12, (f) 𝜆=0.5, and 𝑎=17.
