DeepOtsu: Document enhancement and binarization using iterative deep learning

作者:

Highlights:

• We propose a novel iteration deep learning which can improve the input image iteratively.

• We apply the proposed iterative deep learning for document enhancement and binarization in two possible ways: recurrent refinement and stacked refinement.

• Our proposed method provides a new, clean version of the degraded image, one that is suitable for visualization and which shows promising results for binarization using Otsu’s global threshold.
