摘要：
An approach to sub-pixel edge detection is presented based on spline interpolation and LOG operator. The interested area of the picture is interpolated using spline of D2 with accuracy of 1/n to produce the sub-pixel image. The algorithm is separable in rows and columns. The LOG operators with different sizes are convoluted with the subpixel image to generate edge pictures. The sub-pixel edges are obtained by conjugation.
