Region description and comparative analysis using a tesseral representation

Presents a region representation scheme and comparative analysis methods based on a tesseral addressing system. The proposed scheme is described in the context of a performance analysis of page segmentation methods, a document image analysis area that is particularly sensitive to both a successful region description scheme and efficient methods for comparative analysis. The proposed tesseral representation is more economical in storage than other Cartesian-based approaches and can be advantageous for comparative analysis.
