HMM has been used successfully to model speech and online signature in the past two decades. The success has been attributed to the fact that these biometric traits have time reference. Only few HMM based offline signature recognition systems have be developed because offline signature lack time reference. This paper presents a recognition system for offline signatures using Discrete Cosine Tra...

The notion of on-line/off-line signature schemes was introduced in 1990 by Even, Goldreich and Micali. They presented a general method for converting any signature scheme into an on-line/off-line signature scheme, but their method is not very practical as it increases the length of each signature by a quadratic factor. In this paper we use the recently introduced notion of a trapdoor hash funct...

Mobile ad hoc network (MANET) has been generally regarded as an ideal network model for group communications. However, the security deployment for MANET routing operations is problematic. Firstly, existing secured routing protocols are deficient in achieving both authentication efficiency and full scale of security. In addition, the diversity of routing protocols presents difficulties in the ge...

In this paper, an attempt is made to develop off-line recognition strategies for the isolated Handwritten English character(A to Z) and (0 to 9). Challenges in handwritten character recognition wholly lie in the variation and distortion of handwritten characters, since different people may use different style of handwritten, and direction to draw the same shape of the characters of their known ...

All over India more than 12 crore people utilize Gurumukhi script for speaking, documenting & other purposes. A considerable advancement in the work associated with the recognition of handwritten and printed Gurmukhi text has been reported in last few years. From the last few decades offline handwritten character recognition has gained a lot of interest of researchers. It is well known that eac...

A system for off-line handwritten text recognition is presented. It is characterized by a segmentation-free approach, i.e. whole lines of text are processed by the recognition module. The methods used for pre-processing, feature extraction, and statistical modelling are described, and several experiments on writer-independent, multiple writer, and single writer handwriting recognition tasks are...

Automatic handwritten script identification from document images facilitates many important applications such as sorting, transcription of multilingual documents and indexing of large collection of such images, or as a precursor to optical character recognition (OCR). In this paper, we investigate a texture as a tool for determining the script of handwritten document image, based on the observa...
