Fingerprint identification system is mainly consisted of fingerprint achieving, fingerprint classification and fingerprint matching. Fingerprint matching is the key to the system and effects on the precision and efficiency of the whole system directly. Fingerprints are matched mainly based on their fingerprint texture pattern which can be described with the(More)
The Request-to-Send and Clear-to-Send (RTS/CTS) mechanism was introduced to minimize the collisions due to "Hidden Nodes" in wireless networks. It tried well to solve this problem over Carrier Sense Multiple Access (CSMA), but it gave rise to some more problems. These problems are "Exposed Node Problem", "False Blocking Problem" and "Masked Node Problem".(More)
In this paper, we have applied a new feature extraction technique to calculate only twelve directional feature inputs depending upon the gradients. Features extracted from handwritten characters are directions of pixels with respect to their neighboring pixels. These inputs are given to a back propagation neural network with one hidden layer and one output(More)
Neural Networks are being used for character recognition from last many years but most of the works were reported to English character recognition. Character recognition is one of the applications of pattern recognition, which has enormous scientific and practical interest. Many scientific efforts have been dedicated to pattern recognition problems and much(More)
