| Abstract(in English) | This paper proposes an high-speed and high accuracy method of projective transforming moving images by the use of division of dmain, polynominal expression approximation and recursion formula expression. Since transformed images are generated along a scan line, the transformation formulas with two variables are converted into one with one variable. A domain of the transformation formulas is divided into plural intervals and every interval the formulas is approximated by a polynominal expression. The polynominal expressions which vary with the vartical value are converted into the polynominal expressions with coefficients of the same value. And then the polynominal expressions are converted into recursion expressions. As a result, a projective transformer can be constructed with only adders. Finally, it is shown that boundary values which vary with the vertical value can be expressed by the use of recursion expressions also. |
