Biomedical Image Fusion Using Wavelet & Curvelet Transform
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 1
Abstract
Image fusion is the process of merging two images of the same scene to form a single information as possible. Image fusion is important in many different image processing fields such as satellite imaging, remote sensing and medical imaging. The study in the field of image fusion has evolved to serve the advance in satellite imaging and then, it has been extended to the field of medical imaging. Several fusion algorithms have been proposed extending from the simple averaging to the curvelet transform. Algorithms such as the intensity, hue and saturation (IHS) algorithm and satellite image fusion. The IHS algorithm belongs to the family of color image fusion algorithms. The wavelet fusion algorithm has also succeeded in both satellite and medical image fusion appli the wavelet fusion algorithm is in the fusion of curved shapes. Thus, there is a need for another algorithm that can handle curved shapes efficiently. So, the application of the curvelet transform for curved object image fu result in a better fusion efficiency. A few attempts of curvelet fusion have been made in the fusion of satellite images but no attempts have been made in the fusion of medical images. The main objective of medical imaging is to obtain a high re sake of diagnosis. There are several medical imaging techniques such as the MR and the CT techniques. Both techniques give special sophisticated characteristics of the organ to be imaged. So, it is ex the MR and the CT images of the same organ would result in an integrated image of much more details. Researchers have made few attempts for the fusion of the MR and the CT images. Most of these attempts are directed towards the application of the wavelet transform for this purpose. Due to the limited ability of the wavelet transform to deal with images having curved shapes, the application of the curvelet transform for MR and CT image fusion is presented in this work.
