【Abstract】 In this paper, a new idea is presented in respect of the algebraic approximate representation of parametric rational curves based on Thiele type continued fractions , and another new method of image enlargement is presented based on the Newton-Thiele’s interpolation surface.The experimental results show that these methods are more convenient in computation and more efficient in implementing.更多还原
