Be sure to read to the end. I want you to get good knowledge from Social Work Licensing Board . Google Tech Talk August 25, 2010 ABSTRACT Presented by Craig Knoblock. Maps can be a great source of information for a given geographic region, but they can be difficult to find and even harder to process. A significant problem is that many interesting and useful maps are only available in raster format, and even worse many maps have been poorly scanned and they are often compressed with lossy compression algorithms. Furthermore, for many of these maps there is no meta data providing the geographic coordinates, scale, or projection. Previous research on map processing has developed techniques that typically work on maps from a single map source. In contrast, we have developed a general approach to finding and processing street maps. This includes techniques for discovering maps online, extracting geographic and textual features from maps, using the extracted features to determine the geographic coordinates of a map, and aligning maps with imagery. The resulting system can automatically discover maps for a given region and then process the maps to produce accurately aligned road and text layers. Craig Knoblock is the Director of Information Integration at the Information Sciences Institute, a unit of the University of Southern California (USC), and a Research Professor in the USC Computer Science Department. Dr. Knoblock is also a founder and Chief Scientist of Fetch Technologies, a web extraction and integration provider, and of Geosemble Technologies, which develops ...
