摘要	Due to the existing limited dynamic range a camera cannot reveal all the details in a high-dynamic range scene. In order to solve this problem, this paper presents a multi-exposure fusion method for getting high quality images in high dynamic range scene. First, a set of multi-exposure images is obtained by multiple exposures in a same scene and their brightness condition is analyzed. Then, multi-exposure images under the same scene are decomposed using dual-tree complex wavelet transform (DT-CWT), and their low and high frequency components are obtained. Weight maps according to the brightness condition are assigned to the low components for fusion. Maximizing the region Sum Modified-Laplacian (SML) is adopted for high-frequency components fusing. Finally, the fused image is acquired by subjecting the low and high frequency coefficients to inverse DT-CWT. Experimental results show that the proposed approach generates high quality results with uniform distributed brightness and rich details. The proposed method is efficient and robust in varies scenes.
