基于循环平移NACT的图像融合方法
Image Fusion Method Based on Cycle Spinning Non-Aiiasing Contourlet Transform
摘要
Abstract
Aiming at the weakness of high redundancy and long run time existing in nonsubsampled contourlet transformation, the Non-Aliasing Contourlet Transform(NACT) for image fusion using cycle spinning is proposed. NACT is utilized as the multi-scale transformation to decompose the original images into subbands and cycle spinning is applied to improve the NACT translation invariance and overcome false information of fusion image. Experimental results show that-the method is effective in improving the performance of image fusion and is beret than the method using contourlet or NSCT in objective index, meanwhile visual effect is significantly improved.关键词
