AN IMAGE FUSION FRAMEWORK BASED ON HUMAN VISUAL SYSTEM IN FRAMELET DOMAIN

摘要

In this paper, a novel image fusion algorithm based on framelet transform is presented.nThe core idea is to decompose all the images to be fused into low and high-frequencynbands using framelet transform. For fusion, two different selection strategies are developednand used for low and high-frequency bands. The first strategy is adaptive weightednaverage based on local energy and is applied to fuse the low-frequency bands. In order tonfuse high-frequency bands, a new strategy is developed based on texture while exploitingnthe human visual system characteristics, which can preserve more details in sourcenimages and further improve the quality of fused image. Experimental results demonstratenthe efficiency and better performance than existing image fusion methods both innvisual inspection and objective evaluation criteria.
