EXPOSURE FUSION BY FAST AND ADAPTIVE BIDIMENSIONAL EMPIRICAL MODE DECOMPOSITION

摘要

A new method for fusing a scene of two or more differentrnexposed images is proposed. The process of Fast andrnAdaptive Bidimensional Empirical mode Decompositionrnis adopted in order to decompose the illuminationrncomponent of the input images in their Intrinsic ModernFunctions (IMFs). The features of each image can then berndetected by applying local energy operators within thernIMFs and the final fused image is derived as a collectionrnof features from the input images. Finally, the colorrninformation is selected from the “best exposed” pixels ofrnthe input sequence. Experimental results show that thisrnmethod captures all the features from the input imagesrnwhile the fused images display uniform pixel values in thernentire image region.
