Multi-exposure Image Fusion using No-reference Image-quality Metrics

Images taken by typical digital cameras with fixed exposure often suffer from a lack of details in the underexposed and overexposed regions. Fusing multi-exposed images is particularly useful for improving this situation. This paper proposes a weighted-sum-based multi-exposure image fusion method that is fast enough to be implemented in digital cameras. The proposed method attempts to improve the fusion performance by using recently proposed no-reference imagequality metrics. Experimental results for various sample image sequences show the superiority of the proposed method in terms of subjective evaluation.
