Benchmarking: An Interactive Tool for Vectorization of Raster Images
نویسندگان
چکیده
Methods have been presented to compute the vector representations of the arbitrary lines in a bilevel raster image. The image may have varying line width and irregular boundaries. Moreover, at line crossings and branches, the user has an opportunity to choose the direction in which line tracking may be continued. The usual method involves thresholding, thinning, segmentation, polygonalization, and vectorization of chain codes. Instead, a line-tracking tool is designed using manual and parametric approach; whose results are stored using Drawing Interchange File (DXF) formats. This leads to an efficient benchmarking tool and algorithm, in particular when individual lines have to be interactively extracted from a raster image. Key-Words: Contour following, Geographical information system, Interactive vectorization, Image processing, Image storage using DXF formats, Line tracking, and Raster to vector conversion.

Vector data structure produces smaller file size than raster image because a raster image needs space for all pixels while only point coordinates are stored in vector representation. Raster-to-vector conversion, i.e. vectorization, has key functionalities in Geographic Information Systems (GIS). This study presents a technique converting raster satellite island images into vector data as polygo...
