Multi-focus image fusion based on matching pursuit

Aiming at multi-focus image fusion, a new image fusion algorithm based on matching pursuit is proposed. Through matching pursuit signal decomposition algorithm, distinctive atoms with higher energy are selected from each input registered image to construct fused image. Some problems in traditional image fusion methods, such as ringing effect or blocking artifacts, can be avoided effectively. The last comparative experiments show that the proposed MP based image fusion algorithm outperforms the traditional wavelet image fusion.
