Computer aided fusion of multi modality medical images provides a very promising diagnostic tool with numerous clinical applications. The objective of this paper is to present a novel scheme of medical imaging fusion. We define ??local to be fused?? of the process of image fusion as a generalized local, which extends airspace locals to generalized locals, and promotes the airspace local priority to...
Performance evaluation method that can compare and analyze different fusion techniques is an essential part in the development of image fusion techniques. This paper mainly discusses the applications and restrictions of performance evaluation metrics such as statistics feature related, information theory related, correlation information entropy, information deviation and etc. Accurate and effective...
Image fusion is becoming one of the hottest techniques in image processing. The paper proposes a shared chain mutual information concept to quantitatively and objectively evaluate the performances of difference image fusion techniques. Furthermore, the performances of two widely used image fusion techniques, i.e. wavelet transform based fusion and pyramid transform based fusion operating on a typical...
Curvelets denoise approach has been proposed to obtain high quality result images recently. But artifacts often appear in the result images after applying curvelets denoise approach. A fuzzy partition based denoise algorithm was proposed to suppress the artifacts employing result images of curvelets and hidden Markov tree based wavelets denoise approaches. After fuzzy partition was applied to the...
Wavelet Transform (WT) based image fusion techniques have been widely studied and applied in hyperspectral data processing research. Generally, image decomposition, sub-image fusion, and image reconstruction are the main steps for a WT based image fusion. The performances of fusion methods are basically dependent on the fusion scheme and its related transform. In this paper, we mainly discuss the...
The traditional medical image fusion method based on pixel weighting has the problem how to obtain the deciding weights. Using the complementation of the CT andMRI images, an adaptive weighted method based on local priority is proposed. The local brightness and detail information of the two original images is considered and the local priority of the fused image is employed, the more raw information...

Image fusion provides a useful tool to integrate multiple images into a composite image that is more suitable for the purposes of human visual perception and can help us to extract more features. In this paper we compare the wavelets-based schemes which are based on ordinary wavelet transform, wavelet packet analysis and the nonlinear fusion scheme. It is concluded that the nonlinear fusion scheme...
