—Back-Projection (BP) is a costly computational step in tomography image reconstruction such as Positron Emission Tomography (PET). To reduce the computation time, this paper presents a Pipelined, Pre-fetch and Par-allelized Architecture for PET BP (3PA-PET). The key feature of this architecture is its original memory access strategy, masking the high(More)
The reduction of image reconstruction time is needed to spread the use of PET for research and routine clinical practice. In this purpose, this article presents a hardware/software architecture for the acceleration of 3D backprojection based upon an efficient 2D backprojection. This architecture has been designed in order to provide a high level of(More)
The third edition of the " international-Traveling Workshop on Interactions between Sparse models and Technology " (iTWIST) will take place in Aalborg, the 4th largest city in Denmark situated beautifully in the northern part of the country. The workshop venue will be at the Aalborg University campus. One implicit objective of this biennial workshop is to(More)
—In this paper, we present the problem of Non Cooperative Target Recognition (NCTR) as a supervised classification problem. After a brief presentation on the radar acquisition system of range profiles and the problem of recognition, we use a Fuzzy-Logic based algorithm to do this classification maximizing the recognition rate while controling the error(More)
