Offline handwritten signature system works on the scanned image of a signature. Offline handwritten signature verification is a two class pattern recognition problem. For our experimentation purpose, we have developed offline signature datasets of with genuine and forged signature samples. Some commonly used geometric features were extracted from the signature datasets. Sequential Minimization ...

Recognition techniques for printed and handwritten text in scanned documents are significantly different. In this paper, we propose method to automatically identify the signature in the scanned document images. This helps to retrieve the document images based on the signature. A simple region growing algorithm is used to segment the document into a number of patches. A patch is composed of many...

about electronic signatures there are more or less some writings concerning their legal aspect. but in those writings there has been a little attention to credibility and evidential value of the electronic signatures. some questions and ambiguities despite being set before has not been answered at all or answered unsatisfactorily. meanwhile, some authors have made mistakes and some have set tri...

In recent years, along with extraordinary diffusion of internet and growing need of personal identification in many applications, signature verification is considered with interest. This paper proposed an offline signature verification method based on Genetic Algorithm and Fuzzy Min Max Neural Network Classifier with Compensatory Neuron. The proposed method is basically consists of two steps. A...

This article describes a method of an off-line signature recognition by using parameterize Hough transform. From human nature, signatures are performed very fast by the person, and hence have a lot of straight-line segments within them. The faster that a person signs their name, the more straight lines will be present in their signature. To detect the straight lines, the Hough transform is appl...

Signature recognition is the process of verifying a writer’s identity by checking the signature against samples previously stored in the database. Several techniques such as the distance-based and statistical classifiers used for feature extraction on a signature image are not invariant to scaling and rotation and the Scale invariant feature transform (SIFT) though invariant to scaling and rota...

Any agreement or contract between two more parties requires at least one party to employ a signature as evidence of the other parties' identities and means establishing intent. As result, people are curious about Signature Recognition than biometric methods like fingerprint scanning. Utilizing both Fourier Descriptors histogram oriented gradients (HOG) features, this paper presents an efficient...

An approach to recognizing human hand gestures from a monocular temporal sequence of images is presented. Of particular concern is the representation and recognition of hand movements that are used in single handed American Sign Language (ASL). The approach exploits previous linguistic analysis of manual languages that decompose dynamic gestures into their static and dynamic components. The fir...

this article concerned on the study of signature submanifolds for curves under lie group actions se(2), sa(2) and for surfaces under se(3). signature submanifold is a regular submanifold which its coordinate components are dierential invariants of an associated manifold under lie group action, and therefore signature submanifold is a key for solving equivalence problems.
