摘要
提出了一种基于 D2 样条插值和 LOG算子的亚像素边缘检测方法 .将被检测的图像块在 1 /2 p精度上行列分离分别进行一维 D2 样条插值 ,得到亚像素图像 ,然后将不同尺度的 LOG算子与之卷积 。
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 D 2 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.
