Multi-focus image fusion based on non-negative matrix factorization and difference images
An image fusion method via non-negative matrix factorization and difference images is proposed. Temporary fused image is constructed by using non-negative matrix factorization. Difference image?s salient features are used to detect the source image?s focused regions. The new fusion method outperforms the other existing image fusion approaches.
