A computational study of the Fast Marching and the Fast Sweeping methods for the Eikonal equation is given. It is shown that even though Fast Sweeping requires asymptotically less operations than Fast Marching, the latter method is faster than the former for the problems under consideration and for realistic grid sizes. Fully second order generalizations of methods of this type for problems wit...

The paper reports the assessment of CFC-11 abundances in the stratosphere obtained using MIPAS observations in the first two years of operation. The retrieval of CFC-11 abundances from the measured radiances is obtained using an approximated and fast forward model. Even if yet limited to the two year for which consolidated MIPAS data are available, the analysis provides detailed information on ...

introduction: focused assessment with sonography for trauma (fast) is a highly effective first screening tool for initial classification of abdominal trauma patients. the present study was designed to evaluate the outcome of patients with blunt abdominal trauma and positive fast findings. methods: the present prospective cross-sectional study was done on patients over 7 years old with normal ab...

In this paper a new method for determining the search area for motion estimation algorithm based on block matching is suggested. In the proposed method the search area is adaptively found for each block of a frame. This search area is similar to that of the full search (FS) algorithm but smaller for most blocks of a frame. Therefore, the proposed algorithm is analogous to FS in terms of reg...
