Abstract
Image fusion is the process of producing a single image from a set of input images with more complete information and has broad applications in many fields, such as computer vision, automatic object detection, image processing, and remote sensing. In this paper, a pixel level image fusion algorithm based on Independent Component Analysis (ICA) and wavelet transform is proposed. Firstly, we use the 2D discrete wavelet transform in order to extract multiple subband images. and then apply ICA on the subband images to get ICA bases, at last fuse the image by the independent component bases. The results show that it gives promising results as compared to previous methods and performs considerably well across a variety of multi sensor imaging data.
