Ghosting-free DCT based multi-exposure image fusion

Abstract

[eng] We propose a novel algorithm for multi-exposure fusion (MEF). This algorithm decomposes image patches with the DCT transform. Coefficients from patches with different exposure are combined. The luminance and chrominance of the different images are fused separately. The algorithm adapts to dynamic sequences in order to avoid ghosting effects. The initial sequence is processed to be made static before applying the fusion procedure. Experiments with several data sets show that the proposed algorithm performs better than state-of-the-art.
