Image Fusion Based on Weighted Average, Mean Filtering and IHS Transform
CHANG Hua-wen, CHEN Chun-xiang （Department of Electronics and Computer Science, Guilin Institute of Technology, Guilin 541004, China） Abstract: In this paper, a new image fusion method which is based on weighted average, mean filtering and IHS Transform is proposed. The aim of this image fusion technique is reducing the loss of multi-spectral information in the process of image fusion based on ordinary IHS transform. Furthermore, the new method should keep simple. The results of experimentation have proved that this improvement of ordinary IHS transform is more effective.
