A new descriptor for person identity verification based on handwritten strokes off-line analysis
A new descriptor for the verification of people’s identity through the analysis of handwritten text is presented. The proposed descriptor corresponds to a representation of the pattern of writing pressure computed from the ...

Convolutional neural networks for off-line writer identification based on simple graphemes
The writer’s identification/verification problem has traditionally been solved by analyzing complex biometric sources (text pages, paragraphs, words, signatures, etc.). This implies the need for pre-processing techniques, ...

Detection of Parkinson’s disease based on spectrograms of voice recordings and Extreme Learning Machine random weight neural networks
Parkinson’s disease consists in the degeneration of the mesencephalic black substance, affecting the dopaminergic vias. Its causes are varied, including exposure to pesticides, genetic factors and, one of the most influential ...

Off-line writer verification based on simple graphemes
A method to writer verification based on handwritten stroke analysis is presented. The proposed descriptors correspond to an estimation of the pressure applied when writing using the grayscale image of the stroke. These ...

Off-line writer verification based on small segments of handwritten text and convolutional neural networks
This paper proposes a new method for writer identification based on small fragments of handwritten text randomly obtained from a paragraph. The main contribution of this work is to show that small fragments carry enough ...

Off-line writer verification using segments of handwritten samples and SVM
This works presents a method to verify a person identity based on off-line handwritten strokes analysis. Its main contribution is that the descriptors are obtained from the constitutive segments of each grapheme, in contrast ...

Writer verification based on simple graphemes and extreme learning machine approaches
Mora, Marco ; Vásquez, A.; Aubin, Verónica; Salazar, E.; Barrientos, Ricardo ; Hernández-García, Ruber; Vilches-Ponce, Karina (2020)Traditional literature presents complex biometric sources, descriptors, and classifiers to solve the writer's verification problem. The simple graphemes have been studied recently considering classifiers such as multilayer ...
