基于密切值法边缘检测效果的一种定量评价方法

A quantitative evaluation method of edge detection effect based on osculating value method

一个定量的、可行的边缘检测效果评价方法对各种算法的评估有重要意义,文中在边缘检测效果评价问题中引入了密切值法,以经典算法作为标尺,通过计算待评价算法和各常用的检测算子所得数据的密切值,提出了一种定量评价检测效果的方法。密切值法计算复杂度低,且未将图像真实边缘作为已知条件,易于实现,因此在对图像边缘检测算法进行预估时,是一种可行的方法。

It is of great significance to put forward a quantitative and feasible method to evaluate the result of edge detection. A method based on the osculating value method to evaluate the result is proposed, which uses the classical algorithms to calculate the osculating value among these algorithms and the method need to be evaluated, which can be a quantitative assessment. This method is fast in calculating, and do not need the real boundary in advance, therefore, it is useful for pretreatment on effect evaluation of edge detection.
