PT Unknown AU Dimosthenis Karatzas Sergi Robles Lluis Gomez TI An on-line platform for ground truthing and performance evaluation of text extraction systems BT 11th IAPR International Workshop on Document Analysis and Systems PY 2014 BP 242 EP 246 DI 10.1109/DAS.2014.49 AB This paper presents a set of on-line software tools for creating ground truth and calculating performance evaluation metrics for text extraction tasks such as localization, segmentation and recognition. The platform supports the definition of comprehensive ground truth information at different text representation levels while it offers centralised management and quality control of the ground truthing effort. It implements a range of state of the art performance evaluation algorithms and offers functionality for the definition of evaluation scenarios, on-line calculation of various performance metrics and visualisation of the results. Thepresented platform, which comprises the backbone of the ICDAR 2011 (challenge 1) and 2013 (challenges 1 and 2) Robust Reading competitions, is now made available for public use. ER
