Objectives To examine the effect of incomplete, or total elimination of, projection data on computed tomography (CT) images subjected to statistical reconstruction and/or compressed sensing algorithms. Methods Multidetector row CT images were used. The algebraic reconstruction technique (ART) and the maximum likelihood-expectation maximization (ML-EM) method were compared with filtered back-projection...
This paper presents an image inpainting algorithm which relies on the fast global optimal searching. The whole framework of our method is focused on approximating the minimum of the proposed energy function with additional new texture term. We combine four steps in the framework. First, the initialization is carried out layer by layer in a fast way. Second, we use PatchMatch algorithm to realize the...
Functional magnetic resonance imaging (fMRI) has been used for over a decade to study early cortical retinotopic maps in the peripheral visual areas in the human brain. However, few data were about the higher visual area, especially the object selected activation area. Novel mapping stimuli composed of face figures were used to study the extent and layout of multiple retinotopic regions in the fusiform...
