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...
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...
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...
