Principles of Constructing A Performance Evaluation Protocol for Graphics Recognition Algorithms

Graphics recognition is a process that takes as input a raster level image consisting of pixels or a vector level drawing consisting of symbolic primitives. It groups primitives on the input into higher order graphic entities, and identifies them with known objects on the basis of the matching basic features while allowing for parameter variation. The graphic objects that may be recognized from the input include text (character) regions, lines of various shapes (e.g., circular arcs and polylines) and styles (e.g., dashed lines and dash-dotted lines), special symbols, dimension sets, etc.
