Real-life document recognition systems are composed of multiple modules including field extraction, segmentation recognition, and language modeling. Yann LeCun, et al., "Gradient-Based Learning Applied to Document Recognition" http://yann.…

Convolutional Neural Networks, which are specifically designed to deal with the variability of 2D shapes, are shown to outperform all other techniques. Yann LeCun, et al., "Gradient-Based Learning Applied to Document Recognition" http://ya…
