查询词典 iteration

The following central point within a small local region of current tracing point can be obtained based on the influence of neighboring points as well as the smoothness and fairness principle. Finally, a sequential of central points can be traced out efficiently without any iteration and a parametric curve can be reconstructed by interpolating the central points.

The fired nerves and the unfired nerves of PCNN corresponding to pixels of image are considered as target and the background respectively. The between-cluster variance between the target and the background is calculated at each process of iteration.

在PCNN中，具有相似输入的神经元同时发生脉冲，能够弥补输入数据的空间不连贯和幅度上的微小变化，从而较完整地保留图像的区域信息，这对图像分割无疑是非常有利的。

The parameter adjust algorithm is also deduced. The canceling methods are discussed when the unideal factor of the device is known or unknown. The result proves that when the unideal factor of devices is unknown, the parameter solved by the iteration is convergent to that when the unideal factor is known.

最后给出了精度最佳分配的直接分配迭代算法和对偶分配法。

The "compressed sparse row data format" is adopted to save storage and the "mode multiplication" is used to improve the computation efficiency, so that the finite integration equation is obtained with low storage and high efficiency. To solve the finite integration equation, which is a large-scale sparse algebraic eigenvalue problem under the condition specified, the Krylov subspace iteration method is introduced and the shift-invert Arnoldi method is proposed to exclude the unphysical static electro-magnetic solution and get the needed eigensolution around the specified eigenvalue.
