基于密切值法边缘检测效果的一种定量评价方法

摘要

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 e-valuation of edge detection.
