查询词典 morphology

In this paper, a scale space clustering algorithm based on mathematical morphology operators is proposed. The data are firstly converted into a binary image, the noises are then deleted with close open operators. A scale space is constructed with the close operator and structure elements as well as increased size. The connected cells merge with each other with the increasing scale until all of them combine into one.

中文摘要：提出了一种基于数学形态学算子的多尺度聚类方法：首先将数据进行二值图像化处理，利用一次闭开运算去除噪声干扰后再利用逐步增大结构元素的闭运算构建尺度空间，图像内的连通单元集随着尺度上升不断融合，最终全部归并。
