We describe a new approach for evaluating page segmentation algorithms. Unlike techniques that rely on OCR output, our method is region-based: the segmentation output, described a...
A system for the acquisition, storage, indexing, and retrieval of map images is presented. The input to this system are raster images of separate map layers and map composites. A ...
We propose a technique that makes use of a proximity metric for delineating partially or fully bounded regions of a scanned bitmap that depicts a building floor plan. A proximity...

The method herein proposed detects text lines on handwritten pages which may include either lines oriented in several directions, erasures, or annotationsbetween main lines. The m...
—A fast method of handwritten word recognition suitable for real time applications is presented in this paper. Preprocessing, segmentation and feature extraction are implemented ...
A technique is presented that uses visual relationships between word images in a document to improve the recognition of the text it contains. This technique takes advantage of the...
This paper describes substantial advances in the analysis (parsing) of diagrams using constraint grammars. The addition of set types to the grammar and spatial indexing of the dat...
