the fusion of medical images is very useful for clinical application. generally, the pet image indicates the function of tissue and the mri image shows the anatomy of tissue. in this article we fused mri and pet images and the purpose is adding structural information from mri to pet image. the images decomposed with curvelet transform, and then two images fused with applying fusion rules. we us...

The theory of distributed detection is receiving a lot of attention. A common assumption used in previous studies is the conditional independence of the observations. In this paper, the optimization of local decision rules for distributed detection networks with correlated observations is considered. We focus on presenting the detection theory for parallel distributed detection networks with fi...

Baker and Bowler defined a category of algebraic objects called tracts which generalize both partial fields hyperfields. They also notion weak strong matroids over tract F , proved that if is perfect, meaning -vectors -covectors are orthogonal for every matroid then the notions -matroids coincide. We define class strongly fused prove such perfect. show stringent hyperfields fused; in this way, ...
