摘要
提出假高帽变换和多尺度形态学结构元素相结合的方法进行边缘检测。首先说明假高帽变换的基本原理,接着结合多尺度结构元素进行边缘检测,最后依据不同尺度下的图像标准差确定的权值进行边缘融合,得到理想的边缘。该方法有效克服了传统边缘检测方法和经典形态学边缘检测方法的局限性,具有一定的通用性和实用性。
In this paper, we propose an edge detection method combining pseudo top-hat transformation with muhi-scale morphology structure elements. First ,we indicate the rationale of the pseudo top-hat transformation, then we detect edge in combination with multi-scale structure element, finally we unite edge according to the weight derived from image standard deviation in different scales, and the result is perfect. The method effectively overcomes the limitation of traditional edge detection methods and classical morphology edge detection methods, and is of universality and practicability.
