Abstract

This paper presents part of a new DIA performance analysis framework aimed at Layout Analysis algorithm developers. A new region-representation scheme (an interval-based description of isothetic polygons) and a corresponding comparison approach are introduced. These enable fast and accurate geometric comparison of ground-truth with results of page segmentation, improving on current evaluation methods. Complex layouts are accurately described and Layout Analysis methods that handle them can be effectively evaluated. A further benefit of the new approach is that it measures the accuracy of the description of regions, an issue which is important for complex-layouts involving non-text regions.
