A Novel Image Fusion Based on Nonsubsampled Contourlet Transform
Abstract:
The nonsubsampled contourlet transform (NSCT) is not only with multi-scale and localization, but also with multi-direction, anisotropy and shift-invariance. A novel image fusion algorithm based on the NSCT is proposed in this paper, aiming at solving the fusion problem of images. Experimental results demonstrate that the proposed algorithm cannot only extract more important visual information from source images, but also effectively avoid the introduction of artificial information. It outperforms the traditional discrete wavelet transform-based and the Contourlet-based image fusion methods in terms of both visual performance and objective evaluation.
