The back-projection algorithm can adapt to synthetic aperture radar imaging in any mode because of its time-domain imaging characteristics, so it has received increasing attention in scientific research and engineering practice. However, the large enormous of computation of the back-projection algorithm...
Structure from motion and structure from light are usually regarded separately. To combine both methods, using the same images to retrieve three dimensional information about the environment, both methods must work side by side without interfering each other. This research work describes how laser ...
An explicit formula for optimizing the factorisation parameters in the fast factorized backprojection algorithm is given. It is shown that the optimal factorisation basis is given by b = 3, whereas the optimal number of factorisation levels can be easily computed a priori. A numerical example ...
