Extended Exposure Fusion (EEF) is a high dynamic range imaging technique. It was recently proposed as an improvement of an earlier technique called Exposure Fusion (EF), itself widely used thanks to its very good results. But EF has two well-known artifacts: an out-of-range artifact and a low-frequency halo. The extended version solves them, and delivers fused results with enhanced contrast everywhere in the image. We give in this paper a precise description, analysis and implementation of the extended exposure fusion. We notably verify that the artifacts are removed and that the local contrast is improved compared to the original exposure fusion.
