Abstract—Vectorization processes focus on grouping pixels of a raster image into raw line segments, and forming lines, polylines or polygons. To vectorize massive raster images regarding resource and performance problems, we use a distributed HIPI image processing interface based on MapReduce approach. Apache Hadoop is placed at the core of the framework. To realize such … Read more
Süleyman Eken, Ahmet Sayar, Vectorization and Spatial Query Architecture on Island Satellite Images, Procedia Computer Science Journal (ISSN: 1877-0509) by Elsevier, 2012 (Accepted). Abstract: 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. … Read more
Süleyman Eken, Ahmet Sayar, Vectorization Performance Evaluations of Vector-Raster Satellite Image Transfers through Web Services, 36th IEEE Annual Computer Software and Applications Conference – COMPSAC 2012, Izmir/Turkey, 2012. Abstract: Applications containing images include spatial and topological queries not requiring pixel-based information. In such applications, using vector representations of raster images is expected to give better … Read more
