This paper presents a novel solution for the layout segmentation of graphical elements in Business Intelligence
documents. We propose a generalization of the recursive X-Y cut algorithm, which allows for cutting along
arbitrary oblique directions. An intermediate processing step consisting of line and solid region removal is also
necessary due to presence of decorative elements. The output of the proposed segmentation is a hierarchical
structure which allows for the identification of primitives in pie and bar charts. The algorithm was tested on a
database composed of charts from business documents. Results are very promising.
