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.
