A Novel Image Fusion Method via Ratio Weighted and Condition Weighted Based on Shearlet Transform

摘要

In this paper, a new image fusion method is proposed based on the shearlet transform. The new image is reconstructed by image fusion, which provides richer visual information than the original images. The image could be decomposed by shearlet transform in any scale and any direction, and the detail information can be caught easily. The multi-scale and multiple directions decomposition coefficients are obtained through shearlet transformation. The fusion results are analyzed and compared with the measurement of human visual system and objective evaluation. The experiment results show the advantages of the new fusion method compare to other classical fusion algorithm. The simulation results of the multimodal images are adopted to demonstrate that the algorithm based on shearlet transform is able to obtain fused images of higher clarity and complementary information compared with any other methods.
