Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - The paper is organized as follows: In section 2, we describe the no- orientation-discontinuity interfering model based on a Gaussian stochastic model in analyzing the properties of the interfering strokes. In section 3, we describe the improved canny edge detector with an ed- orientation constraint to detect the edges and recover the weak ones of the foreground words and characters; In section 4, we illustrate, discuss and evaluate the experimental results of the proposed method, demonstrating that our algorithm significantly improves the segmentation quality; Section 5 concludes this paper. 2. The norm-orientation-discontinuity interfering stroke model Figure 2 shows three typical samples of original image segments from the original documents and their magnitude of the detected edges respectively. The magnitude of the gradient is converted into the gray level value. The darker the edge is, the larger is the gradient magnitude. It is obvious that the topmost strong edges correspond to foreground edges. It should be noted that, while usually, the foreground writing appears darker than the background image, as shown in sample image Figure 2(a), there are cases where the foreground and background have similar intensities as shown in Figure 2(b), or worst still, the background is more prominent than the foreground as in Figure 2(c). So using only the intensity value is not enough to differentiate the foreground from the background. (a) (b) (c) (d) (e) (f).

Neuware - The Mexican Conference on Pattern Recognition 2010 (MCPR 2010) was the second event organized by the Mexican Association for Computer Vision, N- rocomputing and Robotics (MACVNR). These conferences provide a forum for exchanging scienti c results and experiences, sharing new knowledge, and - creasing the cooperation between research groups in pattern recognition and related areas, in Mexico, as well as international cooperation. MCPR 2010 was held in Puebla, Mexico, it was hosted and sponsored by the Computer Science Department of the National Institute of Astrophysics, Optics and Electronics (INAOE), jointly with the Center for Computing Research of the National Polytechnic Institute (CIC-IPN). From 89 full papers submitted, 39(43.8%) were accepted for publication in theseproceedingsandfor presentationattheconference.Thecontributionsor- inated from 20 di erent countries. The review process was carried out by the Scienti c Committee, composed of internationally recognized scientists, all - perts in their respective elds. The conference bene ted from the contributions made by the invited spe- ers: Edwin Hancock from the Department of Computer Science, University of York (UK); Guozhu Dong from the Data Mining Research Lab, Department of ComputerScienceandEngineering,WrightStateUniversity(USA);andErnesto Bribiesca Correa from the Department of Computer Science of the Center for Research in Applied Mathematics and Systems of the National Autonomous University of Mexico, IIMAS-UNAM (Mexico). We would like to express our sincere gratitude to the invited speakers.
