  • Visual pattern recognition in the years ahead, Procs  
  • by George Nagy — 2004 — ICPR XVII
  • …Conventional classification algorithms have already reached a plateau at the trade-off imposed by the bias due to the structure of the classifier and the variance due to the limited size of the training set. The latter may be alleviated by exploiting known constraints, including class and style prio…

  • Towards a Ptolemaic Model for OCR  
  • by Sriharsha Veeramachaneni, George Nagy
  • …In style-constrained classification often there are only a few samples of each style and class, and the correspondences between styles in the training set and the test set are unknown. To avoid gross misestimates of the classifier parameters it is therefore important to model the pattern distributio…

  • Interactive Document Processing and Digital Libraries  
  • by George Nagy, Daniel Lopresti — 2006 — in Proc. 2nd IEEE International Conference on Document Image Analysis for Libraries, DIAL 2006
  • …We explore connections between digital libraries and interactive document image analysis. Digital libraries can provide useful data and metadata for research in automated document image analysis, and allow unbiased testing of DIA algorithms. With these goals in mind, we suggest criteria for construc…

  • Adaptive Classifiers for Multi-Source OCR  
  • by Sriharsha Veeramachaneni, George Nagy — 2003 — Int’l J. Document Analysis and Recognition
  • …When patterns occur in large groups generated by a single source (style consistent test data), the statistics of the test data differ from those of the training data which consists of patterns from all sources. We present a Gaussian model for continuously distributed sources under which we develop …

  • Evaluation of Model-Based Interactive Flower Recognition  
  • by Jie Zou, George Nagy — 2004 — In: Proceedings of the 17th International Conference on Pattern Recognition. Volume
  • …We introduce the concept of Computer Assisted Visual InterActive Recognition (CAVIAR). In CAVIAR, a parameterized geometrical model serves as the human-computer communication channel. We implemented a flower recognition system and evaluated it on 30 inexperienced subjects. Major conclusions include:…

  • Human-computer interaction for complex pattern recognition problems, to appear  
  • by Jie Zou, George Nagy — 2005 — in Data Complexity in Pattern Recognition, Springer Verlag, Editors: Mitra Basu & Tin Kam
  • …We review some applications of human-computer interaction that alleviate the complexity of visual recognition by partitioning it into human and machine tasks to exploit the differences between human and machine capabilities. Human involvement offers advantages, both in the design of automated patter…

  • Online handwriting recognition using time-order of lexical and signal co-occurrences  
  • by Ashutosh Joshi, George Nagy — 2005 — Lexical and Signal Co-Occurrences”, 12 th Conf .Intl. Graphonomics Soc., Italy 2005
  • …Abstract. Letter-polygram based Symbolic Indirect Correlation is a new method that offers significant advantages for ordered unsegmented signals. However, its application to on-line, cursive handwriting requires solving several difficult problems. (1) Reference strings of words must satisfy certa in…

  • Mobile Interactive Support System for Time-Critical Document Exploitation  
  • by George Nagy, Daniel Lopresti — 2005 — in Proc. Symposium on Document Image Understanding, College Park, MD
  • …Computer Assisted Visual Interactive Recognition, or CAVIAR, has proven to be an effective methodology for integrating human and machine expertise in addressing challenging pattern recognition tasks. In this paper, we examine the application of the CAVIAR paradigm to problems arising in real-time do…

  • by Sriharsha Veeramachaneni, George Nagy — p.8 of 8) / Color: No / Format: Letter / Date: 10/27/2006 6:59:08 AM SPIE USE: ____ DB Check, ____ Prod Check, Notes
  • …Abstract—We formalize the notion of style context, which accounts for the increased accuracy of the field classifiers reported in this journal recently. We argue that style context forms the basis of all order-independent field classification schemes. We distinguish between intraclass style, which u…
