Thispaper deals with various Multi-Focus Image Fusion Techniques in image processing.It is based on the perspective that the blurred image looks peculiar because of the degradation of high frequency information. This is generally caused by the camera optics.The reason is that cameras suffer from limited depthoffield and this causes the image to be focused only on selected areas.The main intenti...

An image fusion is from a combination of two or more source images corresponding to the image information into a single process. The information displayed in the modified image of the combination shows a higher quality. The quality of an image depends on its perception quality, resolution and contrast. In this paper, we have applied Pyramid Decomposition based on image fusion techniques, which ...

A partial differential equation (PDE)-based feature-level image fusion approach is proposed for multisensory image segmentation. The energy functional of the proposed fusion model is a weighted sum of several functionals, each constructed based on the characteristics of the sensor image. The weight selection decides the way that the model handles redundant, conflicting, or complementary informa...

A second order partial differential operator is applied to an image function. By using a multigrid operator known from the so-called approximation property, we derive a new type of multiresolution decomposition of the image. As an example, the Poisson case is treated in-depth. Using the new transform we devise an algorithm for image fusion. The actual recombination is performed on the image fun...

Due to the special imaging model of SAR, its image includes certain special information that unavailable in multispectral image, however, the interpretation of SAR image becomes more difficult than visible image. Therefore, the fusion of SAR image and multispectral image is primarily for the purpose of making better use of SAR image information. For this application, the autoadaptive informatio...

There are two mistakes in this article [1]. On page 523, lines 10–11, the sentence " the value of the SAM is 1, but the value of the ESAM is less than 1 " should be " the value of the SAM is 0, but the value of the ESAM is great than 0 ". Line 12, " but the value of the ESAM is less than 1 " should be " but the value of the ESAM is great than 0 for even n " .

Image fusion is the process of combining information from two or more images of a scene into a single composite image that is more informative and is more suitable for visual perception or computer processing. The objective in image fusion is to reduce uncertainty and minimize redundancy in the output while maximizing relevant information particular to an application or task. Given the same set...
