Pixel- and Fetaure- Level Image Fusion Techniques

Image fusion is a process combining two or more images in to a single composite image that contains complete information for further processing. In this paper, feature level image fusion was developed and evaluated and the results were compared with pixel level image fusion algorithms using fusion quality evaluation metrics. It was concluded that feature level image fusion provides better fusion results at the cost of execution time. Among the pixel level image fusion algorithms, it was observed that DT-CWT based fusion algorithm provides good results.
