摘要
提出了一种新的基于三次Ｂ样条小波的边缘提取算子，该算子通过构造一个目标函数而得到一组最优滤波器的系数，并将这一组系数和以三次Ｂ样条函数作为尺度函数的线性组合作为最优边缘检测算子提取边缘，经验证该算子优于Ｃａｎｎｙ算子．
This paper proposes a new edge detection operator with cubic B spline wavelet.By building an optimum object function,a set of coefficients of the optimum filter is obtained.The optimum edge detction operator used to extract edge is a linear combination between this set of coefficients and the function which uses cubic B spline function as scale.The experimental results show that the proposed operator is better than Canny′s.
