An Overview of Techniques for Graphics Recognition

An overview is presented of algorithms and techniques for document image analysis with an emphasis on those for graphics recognition and interpretation. Topics covered are data capture, segmentation into text and graphics regions, vectorization, identification of graphical primitives, and generation of succinct image interpretations. This paper is primarily survey in nature, but an effort is made to provide information to evaluate and compare techniques, both through reference to more focused articles, as well as through our own experience.
