Abstract: |
This paper studies methods of data
sampling for training of convolutional neural
networks for character recognition. These methods are considered for optical character
recognition of machine readable zone (MRZ) of
documents captured by a mobile phone camera. Advantages and disadvantages of
training on natural and artificial datasets are discussed. In this paper we
describe some set of image transformations and give examples of their
practical implementation. At the end we show how adding artificial examples
(to the training database), generated according to the analysis of
recognition error, improves the quality of recognition. |
