Patent document images maintained by the U.S. patent database have a specific format, in which figures and text descriptions are separated into different sections. This makes it difficult for users to refer to a figure while reading the description or vice versa. The system introduced in this paper is to prepare these patent images for a friendly user browsing interface. The system is able to extract captions and labels from figures. After obtaining captions and labels, figures and the relevant descriptions are linked together. Hence, users are able to easily find the relevant figure by clicking captions or labels in the description, or vice versa.
