Scene Text Recognition from Two-Dimensional Perspective

Understand

Inspired by speech recognition, recent state-of-the-art algorithms mostly consider scene text recognition as a sequence prediction problem.

• Though achieving excellent performance, these methods usually neglect an important fact that text in images are actually distributed in two-dimensional space.
• It is a nature quite different from that of speech, which is essentially a one-dimensional signal.
• In principle, directly compressing features of text into a one-dimensional form may lose useful information and introduce extra noise.
