Multi-sensor Image Fusion for Effective Night Vision through Contourlet Transform and KPCA and Mutual Information
نویسندگان
چکیده
This paper presents a new image fusion algorithm by combining contourlet transform with Kernel Principle Component Analysis to enhance perception in case of night vision applications. Contourlet Transform improves visual perception preserving the edge and texture information as compared to wavelet transform, while Kernel Principle Component Analysis helps to develop effective fusion decision rule for selecting appropriate coefficients for fusion. Additionally, mutual information is used to adjust the contribution of each image in final fused image. Fusion Quality Index is used for image fusion quality evaluation. Experimental results show that the proposed algorithm performs considerably well as compared to previous wavelet and pyramid based fusion approaches.

Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...
