基于稀疏表示的自适应图像融合方法研究
STUDY ON SPARSE REPRESENTATION BASED ADAPTIVE IMAGE FUSION METHODS
摘要
Abstract
Image fusion means combining two or more images or image sequence information about one particular scene taken by different sensors either simultaneously or unsimultaneously,so that the fused image is more analyzable and comprehensible.On the basis of present classical image fusion methods,the paper proposes a new sparse representation based adaptive image fusion algorithm.The method firstly presents two source images as two groups of sparse coefficients by trained over-completed dictionary;then according to coefficient characteristics adaptively chooses fusion rules to fuse coefficients;finally reconstructs fused coefficients and dictionary to obtain the fused image.During sparse representation process the algorithm can effectively avoid the generation of block-effect and can eliminate noises;therefore the image quality is improved.Experimental results show that the proposed method is superior to the other algorithms either at subjective or objective evaluations.关键词
