We have developed a flexible image content retrieval system for silhouette images based on shape similarity. In our approach, a silhouette image is decomposed into primitives, each of which is translated into two sign...

In this paper, we present a mathematical model for evaluating codes and primitives in optical character recognition. The model is based on code eficiency, calculated from its average length and its transmitted informa...

Most conventional document understanding systems use lexicons only in a postprocessing step to verify or correct character recognition results. The authors present a new approach to wordrecognition that uses a lexico...

We present a formal model for processing grayscale images of business forms such as bank cheques. The formal model is based on a new hybrid-based approach namely the base lines. In fact, to segment handwritten and han...

Model-based column segmentation is described. Sequences of horizontal white space across a column are used as the basic features. Structures of columns in a specific publication are described by two levels of regular ...

A new non-hierarchical spatial data structure named four directional adjacency graphs (FDAG) is proposed. In the FDAG vertical and horizontal neighborhood relationship between rectangles is well represented so that structural information can be easily extracted. An application for structural analysis of forms is given, where experiments are conducted with positive results.
There is a large number of documents, including hand-printed maps, where useful information is lost if binarization is performed on the scanned image before further processing. For such documents, methods which utiliz...

A location-,scale-,and orientation-invariant handwritten Chinese character recognition system is proposed. Five invariant features are employed in this study;the main feature is just invariant to rotation, thus a scal...
