The simplest image enhancement method is to use a 1 x 1 neighborhood size. It is a point operation. In this case, the output pixel (‘s’) only depends on the input pixel (‘r’), and the point operation function can be simplified as follows: s = T(r) Where T is the point oper...

In this paper, a fast point cloud reduction algorithm based on farthest point sampling is proposed. The fast marching algorithm is used to expand the sampling area, and the farthest sampling condition is used to select the qualified sampling points. According to the characteristics of point cloud...

Local registration methods, such as those that use NDT or ICP (pcregisterndt or pcregistericp, respectively), require initial estimates for better performance. To obtain an initial estimate, use another sensor such as an inertial measurement unit (IMU) or other forms of odometry. For increased ...
That method outperformed existing state of the art methods in terms of correctness and quality metrics on benchmark dataset. However, the method is likely to introduce false corners, especially for buildings of complex shape, as spurious lines may still exist in the final step. Various definitions...
It includes an implementation of the BKZ reduction algorithm [SE94], including the BKZ-2.0 [CN11] improvements (extreme enumeration pruning, pre-processing of blocks, early termination). Additionally, Slide reduction [GN08] and self dual BKZ [MW16] are supported. ...

4.5). The vacancy disrupts the regular arrangement of atoms, and causes a local increase in the strain energy owing to the minor misalignment in the atom positions. Vacancies in aerospace alloys are formed during solidification and processing. During cooling and solidification, the atoms, which are...
