A robust approach for text detection from natural scene images

作者:

Highlights:

• Several open problems in this topic are discussed and we present our solution.

• Color-enhanced CERs are effective to be candidate-text-connected-components.

• Neural networks work very well for the challenging text/non-text classification.

• The “ambiguity-free learning” strategy addresses the ambiguity problem properly.

• The “divide-and-conquer” strategy solves the size normalization problem well.
