A local iteration algorithm was proposed, which solves the non-separation problem of applying Collage Theorem for finding the appropriate fractal parameters and can gradually converge to final optimization. 提出了一种局部迭代算法,解决了利用拼帖定理确定分形参数时出现的无法分离求解问题,可以逐步收敛到最优解。
For the convenience of its application, the paper gives the iteration relation for solving transient velocity center by the theorem of three centers. 给出了用三心定理求解其速度瞬心的递推关系及其应用实例。
Based on the parallel Halley iteration for finding all multiple zeros of a polynomial in the relevant reference, another convergence theorem is obtained in this paper. 对有关文献所构造的求多项式全部重零点的并行Halley迭代法给出了另一收敛性定理。
Fractal image coding is an efficient compression technique, in which an image is encoded by a contractive transformation whose fixed point is close to the original image, and then is decoded by using the iteration procedure stemmed from the well-known Banach fixed-point theorem. 形图像编码是一种有效压缩技术。在分形编码中,一幅图像由一个不动点接近原始图像的压缩变换来编码,然后由源于Banach不动点定理的迭代过程来解码。
