Multifocus Image Fusion Using Wavelet Transform
As the size and cost of sensors decrease, sensor networks are increasingly becoming an attractive method to collect information in a given area. However, one single sensor is not capable of providing all the required information, either because of their design or because of observational constraints. One possible solution to get all the required information about a particular scene or subject i...
متن کاملA New Multifocus Image Fusion Method Using Contourlet Transform
A new multifocus image fusion approach is presented in this paper. First the contourlet transform is used to decompose the source images into different components. Then, some salient features are extracted from components. In order to extract salient features, spatial frequency is used. Subsequently, the best coefficients from the components are selected by the maximum selection rule. Finally, ...
متن کاملMultifocus Image Fusion Algorithms using Dyadic non-subsampled Contourlet Transform
The dyadic wavelet has good multi-scale edge detection and sub-band correlation features. Contourlet transformation has multi-directional characteristics. So a new dyadic nonsampling contourlet transformation is constructed. Firstly, multi-scale decomposition is performed on source images using dyadic contourlet transform to get high-frequency and low-frequency images. And then, according to th...
متن کاملMultifocus and multispectral image fusion based on pixel significance using discrete cosine harmonic wavelet transform
The energy compaction and multiresolution properties of wavelets have made the image fusion successful in combining important features such as edges and textures from source images without introducing any artifacts for context enhancement and situational awareness. The wavelet transform is visualized as a convolution of wavelet filter coefficients with the image under consideration and is compu...
متن کاملMultifocus image fusion by combining curvelet and wavelet transform
When an image is captured by CCD device, only the objects at focus plane would appear sharp. A practicable way to get an image with all objects in focus is to fuse images acquired with different focus levels of the scene. In this paper, we propose a multifocus image fusion algorithm based on combination of wavelet and curvelet transform. Although the fused results obtained by wavelet or curvele...
