Evaluation Method of Remote Sensing Image Fusion Effect

The performance measure of image fusion is an important problem in the field of image fusion which has a direct impact on the development of image fusion technology. The estimation model for remote-sensing image fusion processing was building, and the state-of-the-art of the objective evaluation and subjective evaluation technology were analyzed in this paper. Multi-sensor image fusion experiment was operated, and the performance measure of image fusion was operated by using correlation coefficients and PNSR. Furthermore, the main problems of image fusion performance measure were studied. The research results will play an important role in the study of image fusion performance measure.
