Signature verification is one of the most widely used biometrics for authentication. The objective of the signature verification system is to discriminate between two classes: the original and the forgery, which are related to intrapersonal and interpersonal variability. Firstly, there exists great variation even between two signatures of the same person. They never start from the same position and neither do they terminate at the same position. Also, the angle of inclination of the signatures, the relative spacing between letters of the signatures, height of letters, all vary even for the same person. Hence it becomes a challenging task to compare between two signatures of the same person. The proposed an offline signature verification system to take care of that, which is based on depth for segmentation of signature image into different parts, after that geometric center of the each segment is find out as the feature point of that segment. The number of feature points extracted from signature image is equivalent to the number segment of the signature image that is produce by specifying value of depth. The classification of the feature points utilizes two statistical parameters like mean and variance. Our proposed model has three stages: image preprocessing, feature point's extraction and classification & verification. The user introduces into the computer through scanned signature images, our technique modifies their quality by image enhancement and noise reduction techniques, to be followed by feature extraction and finally used Euclidean distance model to classification of signature either genuine or forgery. The proposed offline signature verification system used "GPDS360 signature database". General TermsEuclidean distance model, signature verification and recognition,

Research and Development (R&D) project proposals selection is one of the decision-making task commonly found in government funding agencies, universities, research institutes, and technology intensive companies. With the rapid development of research work in projects, research project selection & classification into different domain is a necessary task for the research funding agencies. It is common to group the large number of research proposals, received by the research funding agencies based on their similarities into research discipline areas. Text Mining has emerged as a definitive technique for extracting the unknown information from large text document for the proposal classification. Ontology is a knowledge repository in which concepts and terms are defined as well as relationships between these concepts. Thus, ontology can automate information processing and can facilitate text mining in a specific domain (such as research project selection). This paper presents approach towards ontology-based text-mining to cluster research proposals based on their similarities in research areas. The method also includes an optimization model for balancing proposals by geographical regions. The grouped proposals are then assign to the appropriate research experts for peer-review through system itself. The proposed method is milestone over the manual approach for classifying proposals.
