摘要
Abstract
The principle of nonsubsampled Contourlet transform and the advantage of multi-scale,localization directionality and anisotro-py are studied in the paper. A new multi-focus image fusion algorithm based on NSCT is developed. Firstly,two different multi-focus source images are decomposed by NSCT. Secondly,different fusion rules are applied in the low and banpass subband coefficients. A new fusion algorithm based on the gray morphology grad operator is applied in lowpass subbands and the consistency check is proposed. The regional energy fusion rule is applied in highpass subbands. Finally,the fused image is reconstructed by the inverse NSCT. The experimental results show that,compared with other algorithms,this fusion method can retain the information and features of source more effectively.关键词
