The Stroke width is an important and stablefeature to describe the texts in the document images. In thispaper, we propose a method for finding stroke width variety incity map images. Since in city maps the graphics lines and textlabels are usually overlap with each other, it is difficult to findthe stroke width in such images. On the other hand, texts areprinted in a variety of widths. Knowing the major text strokewidth is a prior knowledge before map processing like textextraction from graphics lines. In the proposed method, we findthe candidate connected components that have significant strokewidthinformation. Then we locally assign a minimum strokewidth to each pixel. For each candidate component, stroke widthis determined. By clustering stroke width of components, we findmajor stroke widths. The experimental results on severalvarieties of city maps are reported and shown to be promising.<\div>
