The domain of colour text image analysis (real scenes, Web and spam images, scanned colour documents) has traditionally suffered from a lack of a comprehensive performance evaluation framework. Such a framework is extremely difficult to specify, and corresponding pixel-level accurate information tedious to define. In this paper we discuss the challenges and technical issues associated with developing such a framework. Then, we describe a complete framework for the evaluation of text extraction methods at multiple levels, provide a detailed ground-truth specification and present a case study on how this framework can be used in a real-life situation.", optnote="DAG", optnote="exported from refbase (http://refbase.cvc.uab.es/show.php?record=1432), last updated on Mon, 15 May 2017 10:20:11 +0200", isbn="978-1-60558-773-8", doi="10.1145/1815330.1815333" }
