How to use STN to rectify a distorted text imge

[Lesley96-11]

Hello sir,I'm trying to use CRNN to recognize chinese, and before recognize, I want to rectify the distorted text region. And I found that your network used STN in the detection part,will it rectify text region? and I don't know how to use STN directly.

Hi,

you should be able to use this network to perform rectification of already cropped scene text with this model. But this model works in such a way, that it tries to detect every single character and then rectify this character. There is other related work that rectifies cropped text-lines using STNs but a slightly different approach (Robust scene text recognition with automatic rectification.
