The Architecture of Trueviz: a Groundtruth/metadata Editing and Visualizing Toolkit the Architecture of Trueviz: a Groundtruth/metadata Editing and Visualizing Toolkit the Architecture of Trueviz: a Groundtruth/metadata Editing and Visualizing Toolkit

Tools for visualizing and creating groundtruth and metadata are crucial for document image analysis research. In this paper we describe TrueViz [LK00, KLCB01], which is a tool for visualizing and editing groundtruth/metadata. We rst describe the groundtruthing task and the requirements for any interactive groundtruthing tool. Next we describe the system design of TrueViz and discuss how a user can use it to create groundtruth. TrueViz is implemented in the Java programming language and works on various platforms including Windows and Unix. TrueViz reads and stores groundtruth/metadata in XML format, and reads a corresponding image stored in TIFF image le format. Multilingual text editing, display, and search modules based on the Unicode representation for text are also provided. This software is being made available free of charge to researchers.
