In this paper, a new method for offline handwriting recognition is presented. A robust algorithm for handwriting segmentation has been described here with the help of which individual characters can be segmented from a word selected from a paragraph of handwritten text image which is given as input to the module. Then each of the segmented characters are(More)
In wireless communication, broadcasting is one of the most suitable solutions of information dissemination. It is very attractive for limited resource handheld mobile devices in asymmetric communications. Access time and Tuning time are two criteria to evaluate the performance of air indexing technique. Indexing can reduce tuning time of the mobile devices(More)
The Self-organizing map (SOM) has been extensively applied to image analysis, data clustering, dimension reduction, and so forth. The conventional SOM find the winner neuron and update the weights of winner and its neighborhood regardless of distance from input. In this study, we propose a modified SOM which calculate the distance from input data and find(More)
The Self-organizing map (SOM) has been extensively applied to data clustering, image analysis, dimension reduction, and so forth. The conventional SOM does not calculate the winning frequency of each neuron. In this study, we propose a modified SOM which calculate the winning frequency of each neuron. We investigate the behavior of modified SOM in detail.(More)
1 In a conventional SOM, it is of utmost importance that a certain and consistently decreasing learning rate function be chosen. Decrease the learning rate too fast, the map will not get converged and the performance of the SOM may take a steep fall, and if too slow, the procedure would take a large amount of time to get carried out. For overcoming this(More)
" Hindi " the national language of India (written in Devanagri script) is world " s third most popular language after Chinese and English Hindi handwritten character recognition has got lot of application in different fields like postal address reading, cheque reading electronically. Recognition of handwritten Hindi characters by computer machine is(More)
Mobile device has limited battery power, the minimization of the access time and tuning time for the broadcast data is an important problem. There have been many research efforts that focus on minimizing access time and tuning time by providing indexes on the broadcast data. This paper proposes two level energy efficient signatures indexing techniques over(More)
