In this paper, a total variation (TV) minimization strategy is proposed to overcome the problem of sparse spatial resolution and large amounts of noise in low dose positron emission tomography (PET) imaging reconstruction. Two types of objective function were established based on two statistical models of measured PET data, least-square (LS) TV for the Gaussian distribution and Poisson-TV for t...

In this paper, we propose a method for dynamic integration of TV-program content and related web content and demonstrate our prototype system called WebTelop . The primary source of information in WebTelop is the TV-program content. Web pages related to the TV-program content are retrieved automatically in real time and are used to augment the TV-program content in the form of captions. Our met...
