A locally adaptive, diffusion based text binarization technique

作者:

Highlights:

• Novel adaptive binarization technique based on linear diffusion with a nonlinear source term.

• Extremely low sensitivity to noise.

• Excellent results and stability compared to existing techniques.

• Results have been compared with the state-of-the-art techniques presented in DIBCO.
