This performance can be expressed by lower rejection rates and higher recognition rates. The used methods range from voting schemes based on results of different recognizer to a neural network decision based on normalized confidences. This work presents an extension of the well known combination methods for a large lexicon, an extension from maximum 30 classes (e.g., 10 classes for digits classification) to 937 classes for the IfN/ENIT-database. In addition, different reject rules based on the evaluation and analysis of individual and combined systems output are discussed. Different threshold function for reject levels are tested and evaluated. Tests with a set of recognizer, which participated in the ICDAR 2007 competition and based on set coming from the IfN/ENIT-database show that a word error rate (WER) of 5.29% without reject and with a reject rate less than 25% even a word error rate of less than 1%.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...

We experimentally compare different time-series clustering methods and find out that the proposed prototype with agglomerative clustering followed by k-means algorithm provides best clustering accuracy.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...

The algorithm is included into a surveillance system which tracks and classifies objects and transmits this information to a higher computational level which fuses the information of several cameras covering overlapping areas. Two kind of features are used: foreground density features and features related to real-size of objects, obtained by applying a homographic model. A classification schema based on k-nn classifiers and a voting system makes the classification process highly robust. On-line and off-line experiments are introduced.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ... IAPR International Conference on Pattern Recognition.

In order to use it, a background model must be built and updated according to light and scenario changes. We discuss in this paper a new algorithm (BAC) which creates or restores a background model based on the behaviour of pixels in successive frames, while performs a segmentation of objects in the scene yielding a confidence value for the obtained background, a problem which is addressed by few methods in the literature. This allows us to fulfil the requirement of producing a model, for instance in scenarios like airport halls, without interfering normal operation and still segment scenes.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...
