Scene Text Recognition with Permuted Autoregressive Sequence Models

Bautista, Darwin, Atienza, Rowel

Understand

Context-aware STR methods typically use internal autoregressive (AR) language models (LM).

  • Inherent limitations of AR models motivated two-stage methods which employ an external LM.
  • The conditional independence of the external LM on the input image may cause it to erroneously rectify correct predictions, leading to significant inefficiencies.
  • Our method, PARSeq, learns an ensemble of internal AR LMs with shared weights using Permutation Language Modeling.
