Stanford University Libraries Study: Topographical Map Vectorization and the Impact of Bayer Moire Defect

摘要

The discovery of defects in Stanford University Library's topographical map raster image files prompted a study of the impact of Bayer moire on vectorization. An analysis of findings has supported developing a better understanding of color filter array technology and some of its associated quality issues: rationales for on-demand file remediation of affected image files, options for map imaging in the future, an effective and open-source approach for vectorization, performance improvements for producing and vectorizing raster images. Additional quality control measures for imaging large maps, and a refinement of the topo raster image specification are also shared.
