REPORT chen-0218/IDIAP Video Text Recognition Based on Markov Random Field and Grayscale Consistency Constraint Odobez, Jean-Marc Chen, Datong EXTERNAL http://publications.idiap.ch/attachments/reports/2002/rr-02-18.pdf PUBLIC Idiap-RR-18-2002 2002 IDIAP April 2002 Published in Proceedings of the Int. Conf. Image Processing 2002 A method for segmenting and recognizing text embedded in video and images is proposed in this paper. In the method, multiple segmentation hypotheses of text image are first generated based on a MRF model. Background regions in each hypothesis are then removed by using grayscale consistency constraint (GCC) in a connected component analysis procudure before being processed by an optical character recognition (OCR) software.
