Fast Exposure Fusion Using Exposedness Function

We propose a fast and effective method for multi-exposure image fusion. Our method blends multiple exposures under a base-detail decomposition of input images. Construction of blending weights in the proposed method is performed based on an exposedness function using luminance component of the input images. The fused base layer and detail layer are integrated into the final fused image which its detail strength is simply controlled through the integration process. Experimental results demonstrate that the proposed exposure fusion method is much faster than competing methods and can achieve state-of-the-art performance objectively and perceptually.
