Fractals based multi-oriented text detection system for recognition in mobile video images

作者：

Highlights：

• Fractal property, such as self-similarity has been explored for text detection.

• Fractal expansion is explored further for detecting text candidates.

• Optical flow is proposed for false positive elimination.

• Experiments are conducted on benchmark databases for evaluating method.
