Abstract
This paper describes the specifications for our ground-truthed mathematical character and symbol image database, called InftyCDB-1. The ground-truth of each character is composed of type, font, quality (touched/broken) and link (relative position), etc. The database includes all the characters and symbols of 467 pages of 30 articles on mathematics, and is organized so that it can be used as word image database or as mathematical formula image database. InftyCDB-1 is a public database that is freely usable for research and development purposes.Keywords
