The paper presents a numerical reconstruction method of digital holography based on graphic processing unit with MATLAB, which can obtain a calculation speed about 41 times faster than a CPU alone and make real-time system possible.
We consider the task of creating a 3-d model of a large novel environment, given only a small number of images of the scene. This is a difficult problem, because if the images are taken from very different viewpoints or if they contain similar-looking structures, then most geometric reconstruction methods will have great difficulty finding good correspondences. Further, the reconstructions given by...
In classical rough set theory, which gives definitions of indiscernibility relation, upper approximation, lower approximation, reduct and core, the main idea is approximating knowledge granules which come from decision attributes set employing knowledge granules from condition attributes set, hence generating rules. These knowledge granules are obtained according to equivalence relation in essence,...
