摘要
从Canny最优边缘检测准则出发 ,分析了中心B样条二进小波与最优准则的关系 ,给出了多尺度边缘提取时二进小波的构造 .结果表明四阶中心B样条函数的导数比Canny算子更接近最优边缘检测准则 。
Based on the optimum criterions of edges detection proposed by Canny,the relation between center B spline dyadic wavelet and optimum criterions is analyzed.The structure of dyadic wavelet used in multiscale edges detection is provided.Results show that derivative of center B spline function can satisfy the optimum criterions more approximately and has higher speed than Canny operator.$$$$
