TS-Net: OCR Trained to Switch Between Text Transcription Styles
Multiple transcribers produce transcriptions in inconsistent transcription styles.
This presents a problem for training consistent neural network systems for text recognition.
We propose Transcription Style Block (TSB) which can learn to switch between multiple transcription styles without any explicit knowledge about the transcription rules.
TSB is an adaptive instance normalization conditioned by transcription style identifiers e.g. document numbers or transcriber names and it can be added near the end of any standard text recognition network.
We show that TSB is robust towards the number and complexity of transcription styles and does not degrade the text recognition performance.
With time and data efficient adaptation to a new transcription style, we achieved up to 77\% relative test character error reduction in comparison to a network without the TSB.
