Background Volume estimation of brain is important for many neurological applications. It is necessary in measuring brain growth and changes in brain in normal/abnormal patients. Thus, accurate brain volume measurement is very important. Magnetic resonance imaging (MRI) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. Ste...
abstract: research purpose: the purpose of this research is to identify academic databases assessment factors and criteria at law and political science majors. the necessity of this research is to distinguish academic databases assessment factors and criteria and to identify the most important ones and rank them in order to select an appropriate database according to students’ and faculty memb...
Abstract Magnetic Resonance Imaging (MRI) is widely adopted in medical diagnosis. Due to the spatial coding scheme, MRI image degraded by various noise. Recently, massive methods have been applied denoising. However, they lack consideration of artifacts images. In this paper, we propose an unsupervised denoising method called UEGAN based on decoupled expression. We decouple content and noise a ...
• Development of a learning-based approach to compute T1, T2, and PD maps from clinical routine sequences. Computation three realistic parametric only two input images (a three-from-two approach). Realistic are obtained actual data by training the network with synthetic dataset. weighted pertaining modalities unseen maps. Quantitative MRI in viable times. Background Objective: Synthetic magneti...
Segmentation is an essential requirement in medicine when digital images are used illness diagnosis, especially, posterior tasks as analysis and disease identification. An efficient segmentation of brain Magnetic Resonance Images (MRIs) prime concern to radiologists due their poor illumination other conditions related de acquisition the images. Thresholding a popular method for that uses histog...
Introduction: The Iranian Brain Imaging Database (IBID) was initiated in 2017, with 5 major goals: provide researchers easy access to a neuroimaging database, provide normative quantitative measures of the brain for clinical research purposes, study the aging profile of the brain, examine the association of brain structure and function, and join the ENIGMA consortium. Many prestigious databases...

Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...
A critical issue in image restoration is the problem of noise removal while keeping the integrity of relevant image information. The method proposed in this paper is a fully automatic 3D blockwise version of the nonlocal (NL) means filter with wavelet subbands mixing. The proposed wavelet subbands mixing is based on a multiresolution approach for improving the quality of image denoising filter....
