Arbitrary orientation and sparse data content are common characteristics of torn document. To ensure accuracy and reliability in computer-based analysis, content-zone segmentation is required. In our previous work, we studied segmentation of handwritten and printed text. A questioned document-piece in the form of an office note, however, might also contain non-text data like logos, graphics, and pictures...
Performance of a pattern recognition system depends strongly on the employed feature-selection method. We perform an in-depth analysis of two main measures used in the filter model: the correlation-feature-selection (CFS) measure and the minimal-redundancy-maximal-relevance (mRMR) measure. We show that these measures can be fused and generalized into a generic feature-selection (GeFS) measure. Further...
The quality of the feature selection algorithm is one of the most important factors that affects the effectiveness of an intrusion detection system (IDS). Achieving reduction of the number of relevant traffic features without negative effect on classification accuracy is a goal that greatly improves the overall effectiveness of the IDS. Obtaining a good feature set automatically without involving...
A two-stage approach for word-wise identification of English (Roman), Devnagari and Bengali (Bangla) scripts is proposed. This approach balances the tradeoff between recognition accuracy and processing speed. The 1st stage allows identifying scripts with high speed, yet less accuracy when dealing with noisy data. The advanced 2nd stage processes only those samples that yield low recognition confidence...
