Security is an important concern for today's generation, where keystroke-scan had come out as a milestone. In this paper, a comparison approach is presented for user authentication using keystroke dynamics. Here we have shown the effect of Dimensionality Reduction techniques on the performance and the misclassification rate is between 9.17% and 9.53%. It helps in improving the performance of the system...
The project of converting Indian language document to Bharti Braille script has many challenges. The illumination invariant character recognition is one of such challenge which is addressed in this paper. The Gabor features provide illumination invariance up to certain extend, but in recent developments such as local binary pattern and binarizing the directional filter's response and then computing...
The artificial neural network is typically trained from initial weight/bias position. As training progresses the network parameters such as weights and biases are updated according to learning algorithm to reduce the performance index. Not all the network parameters are equally learning the input-output mapping. Some parameters would hold more discriminating capability while others are not so effective...
