Multi-modality medical image fusion based on separable dictionary learning and Gabor filtering
Qiu Hu,Shaohai Hu,Fengzhen Zhang +2 more
TL;DR: A novel fusion method that combines separable dictionary optimization with Gabor filter in non-subsampled contourlet transform (NSCT) domain is proposed, leading to the state-of-art performance on both visual quality and objective assessment.

Multi-modality image fusion combining sparse representation with guidance filtering
Qiu Hu,Shaohai Hu,Fengzhen Zhang +2 more
TL;DR: In this article, an improved guided image filtering (GIF)-based weighted average via Gabor energy is put forward for the fusion of base layers contained large scale structure information, and a sparse representation-based separable dictionary learning is recommended to capture small scale detailed information of detail layers.
