Multisource Image Fusion Based on Wavelet Transform
نویسندگان
چکیده
This paper clarifies the concepts and relationship between image fusion rules and operators based on wavelet transform. According to wavelet decomposition characteristic, a new strategy of calculating spatial frequency is put forward. Fusion experiments are performed on QuickBird panchromatic (PAN)and multispectral (MS) images based on orthogonal and biorthogonal wavelet, in which a method of comparing activity level of spatial frequency is introduced for the detail coefficient fusion. Finally, the influence of the wavelet decomposition level and support width on the results of fusion is discussed in detail.

Review on Different Methods of Multisource Image Fusion Techniques
The objective of image fusion is to combine information from multiple images of the same scene. The result of image fusion is a new image which is more suitable for human and machine perception or further image-processing tasks such as segmentation, feature extraction and object recognition. Different fusion methods have been proposed in literature, including multiresolution analysis. The doubl...
متن کاملFusion of Thermal Infrared and Visible Images Based on Multi-scale Transform and Sparse Representation
Due to the differences between the visible and thermal infrared images, combination of these two types of images is essential for better understanding the characteristics of targets and the environment. Thermal infrared images have most importance to distinguish targets from the background based on the radiation differences, which work well in all-weather and day/night conditions also in land s...
متن کاملMultisource Images Adaptive Fusion Based on Double Density Dual-tree Complex Wavelet Transform
Double density dual-tree complex wavelet transform (DD-DTCWT) as multiscale decomposition tool provides multiresolution and multidirection expansion for images. Compared with the discrete wavelet transform (DWT), it is shift-invariant and can overcome the detail blur and pseudo-Gibbs phenomena. Fusion rule is the key that influences the quality of image fusion. This paper propose a fusion rule ...

متن کاملMultimodal medical image fusion based on Yager’s intuitionistic fuzzy sets
The objective of image fusion for medical images is to combine multiple images obtained from various sources into a single image suitable for better diagnosis. Most of the state-of-the-art image fusing technique is based on nonfuzzy sets, and the fused image so obtained lags with complementary information. Intuitionistic fuzzy sets (IFS) are determined to be more suitable for civilian, and medi...
