A method to improve the image enhancement result based on image fusion

Image enhancement can improve the perception of information. An image taken from a real scene can be divided into several regions according to the need for enhancement. One particular enhancement method improves some regions and actually deteriorates the other regions which have no need for such enhancement or any enhancement at all. This paper proposes a method to improve the enhancement result with image fusion method with evaluation on sharpness. Several different evaluation methods and fusion policies are discussed and compared. The experiment results show that the fusion improves the enhancement results.
