A Study on Multi-Focus Image Fusion Based on NSCT and Focused Area Detection
In this paper, a study on multi-focus image fusion methods having the ability to conquer the problems in transform domain method and to avoid the disabilities occurring in spatial domain method has been introduced. To gain an image with high quality and with all spectral and spatial information, it is important to recover the images from various multi-sensor images. Image fusions are mainly cla...
متن کاملMulti-focus Image Fusion Using Spatial Frequency and Genetic Algorithm
We introduce in this paper a region based multi-focus image fusion algorithm using spatial frequency and genetic algorithm. The basic idea is to divide the source images into blocks, and then select the corresponding blocks with higher spatial frequency value to construct the resultant fused image. GA is brought forward to determine the suitable sizes of the block.
متن کاملMulti-focus Image Fusion using the Local Neighbor Sum of Laplacian in NSCT Domain
To suppress the Pseudo-Gibbs phenomena caused by the Contourlet, the Nonsubsampled Pyramids Filter Banks and the Nonsubsampled Directional Filter Banks are combined to construct the nonsubsampled Contourlet transform (NSCT). Hence, The NSCT not only possess the main features of multi-scale, multi-directional and timefrequency localization, but also offer the property of the shift-invariant whic...
متن کاملA Multi-Focus Image Fusion Algorithm Based on Contrast Pyramids
This paper proposes a new approach for multi-focus images fusion based on Region Mosaicing on Contrast Pyramids (REMCP). A density-based region growing method is developed to construct a focused region mask for multi-focus images. The segmented focused region mask is decomposed into a mask pyramid, which is then used for supervised region mosaicking on a contrast pyramid. In this way, the focus...
متن کاملMulti-Focus Image Fusion in DCT Domain using Variance and Energy of Laplacian and Correlation Coefficient for Visual Sensor Networks
The purpose of multi-focus image fusion is gathering the essential information and the focused parts from the input multi-focus images into a single image. These multi-focus images are captured with different depths of focus of cameras. A lot of multi-focus image fusion techniques have been introduced using considering the focus measurement in the spatial domain. However, the multi-focus image ...
