In this paper weconsider the problem of character segmentation. Image processing methods are widely used in various specialized algorithms, whichcannot solve the problem entirely. In some papers authors use different customizations based on the structures on the image and improve the final segmentation on the basis of knowledge about the alphabet and the font. However, such algorithms can be complicated and too non-robusttowards the alphabet and the font of the text.We suggest the neural network encoder learning approach instead of classic method for cuts estimation between characters. We demonstrate the effectiveness of this approach using strings from RF passport fields as an example and show the advantages of the suggested approach over the classic one.

Key words: convolutional neural networks, deep learning, text segmentation, cumulative sum
