Convolutional neural networks for off-line writer identification based on simple graphemes
Mora, Marco; ; (2020)
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, ...
