However, systems aimed at overcoming the semantic gap between the visual description of patent images and their conveyed concepts would be very helpful for patent professionals. In this paper we present a flowchart recognition method aimed at achieving a structured representation of flowchart images that can be further queried semantically. The proposed method was submitted to the CLEF-IP 2012 flowchart recognition task. We report the obtained results on this dataset. %K Flowchart recognition %K Patent documents %K Text/graphics separation %K Raster-to-vector conversion %K Symbol recognition %U http://refbase.cvc.uab.es/files/RHR2013.pdf %U http://dx.doi.org/10.1007/s10791-013-9234-3 %P 545-562
