ABSTRACT:
A method and system for generation of a quadratic curve signal expressed by f(x, y)=0 nonparametrically on coordinates X, Y, wherein, when linear micro-coefficients in the directions x, y are points (x, y) are given as fx, fy, respectively, the signs of fx, fy are decided and fx, fy are compared for dimensions with each other, thereby limiting the point to be selected next, to two points; then the value of new f(x,y) obtainable through selecting each point, are calculated; absolute values of the new f(x, y) are compared, the point giving the smaller value being selected as the next point; and repeating the aforementioned procedure, thereby to generate a quadratic curve signal expressed by f(x, y)=0.
