It also uses Cartesian grids, called inverse maps, to improve the efficiency of selecting starting points for the search for interpolation stencils. These techniques improve the efficiency of the grid assembly process; however, an additional burden is placed on the user to define the analytical ...

We have developed an open-source software package, Open-source Seismic Wave Propagation Code (OpenSWPC), for parallel numerical simulations of seismic wave propagation in 3D and 2D (P-SV and SH) viscoelastic media based on the finite difference method in
resulting output pixel is calculated through a bilinear interpolation of these transformed coordinates. • Contrast A pixel-wise kernel applies a parameterized contrast enhancement of an image. • Convolution 5×5; 3×3 Convolution kernels using a 5×5 or 3×3 mask imple- mented without loops...
We separately time the efficiency of the PetSc solver and of the OpenFPM parts of the code (particle-mesh/mesh-particle interpolation, remeshing, time integration, right-hand side evaluation). The results are shown in Fig. 10. Within a cluster node (1…24 cores), the decay in efficiency ...
The normalized parameter of the B-spline curve is considered to divide the whole model into two submodels. In the first submodel, the satisfaction function is proposed to convert energy and jerk indices into one comprehensive objective for optimization with the quantum-behaved particle swarm ...
A commonly used approach for data interpolation, relies on defining in mathematical terms a three dimensional curve using existing pixel data and from that curve calculating intermediate pixel values. Existing pixel values are obtained from a defined area surrounding the area to be filled in, and th...
After a phase mapping,aparallelogram linear interpolationwas carried out along the edge directions in the edge regions. 最后在边缘区域内边缘方向进行相位映射后,进行平行四边形线性插值。 6) parallel line 平行边 1. This essay deduces the definition of adjacency matrix of directed graph in the cuses...
